Stefan Metzmacher 89b021a726 smb: server: manage recv credits by counting posted recv_io and granted credits 
(At least for me) the logic maintaining the count of posted
recv_io messages and the count of granted credits is much
easier to understand.

From there we can easily calculate the number of new_credits we'll
grant to the peer in outgoing send_io messages.

This will simplify the move to common logic that can be
shared between client and server in the following patches.

Stefan Metzmacher 113ed9d56f smb: server: take the recv_credit_target from the negotiate req and always limit the range 
The clients sends the initial recv_credit_target in the negotiate req,
so we should use that.

We also limit the range between 1 and our local defined
sp->recv_credit_max. This will simplify further logic changes.

Stefan Metzmacher b31606097d smb: server: move smb_direct_disconnect_rdma_work() into free_transport() 
The logic is also needed when smb_direct_handle_connect_request()
calls free_transport(), because rdma_accept() and RDMA_CM_EVENT_ESTABLISHED
could already be reached.

Stefan Metzmacher e2d5e516c6 smb: server: only turn into SMBDIRECT_SOCKET_CONNECTED when negotiation is done 
From SMBDIRECT_SOCKET_CREATED we now go via the following
stages:

1. SMBDIRECT_SOCKET_RDMA_CONNECT_NEEDED
   This indicated rdma_accept needs to be called

2. SMBDIRECT_SOCKET_RDMA_CONNECT_RUNNING
   This waits for RDMA_CM_EVENT_ESTABLISHED to
   arrive

3. SMBDIRECT_SOCKET_NEGOTIATE_NEEDED
   This waits for the negotiate request to
   arrive

4. SMBDIRECT_SOCKET_NEGOTIATE_RUNNING
   This indicates the negotiate request
   arrived and needs to be processed

5. SMBDIRECT_SOCKET_CONNECTED
   The connection is ready to use

This avoids the extra 'bool negotiation_requested'
and makes the steps more clear.

In future we may want to add trace points when
changing the states, which would be useful for
debugging.

Stefan Metzmacher a7eef6144c smb: server: queue post_recv_credits_work in put_recvmsg() and avoid count_avail_recvmsg 
This is basically what the client is doing in put_receive_buffer().

It means we don't need complicated work to maintain count_avail_recvmsg.

But we keep the logic to queue post_recv_credits_work if the
peer raises the requested credit_target and put_receive_buffer()
is not called.

Stefan Metzmacher d4b86b4909 smb: server: add a pr_info() when the server starts running 
We already have a message like:
ksmbd: kill command received
when the server stops running.

This makes it easier for debugging in order to match any possible
warnings/errors in dmesg with restarted server.
