Mike Marciniszyn fc3f15c672 IB/hfi1: Add limit test for RC/UC send via loopback ...

commit 09ce351dff upstream.

Fix potential memory corruption and panic in loopback for IB_WR_SEND
variants.

The code blindly assumes the posted length will fit in the fetched rwqe,
which is not a valid assumption.

Fix by adding a limit test, and triggering the appropriate send completion
and putting the QP in an error state.  This mimics the handling for
non-loopback QPs.

Fixes: 1570346153 ("IB/{hfi1, qib, rdmavt}: Move ruc_loopback to rdmavt")
