Niels Dossche ce237c1e25 Bluetooth: use hdev lock for accept_list and reject_list in conn req ...

[ Upstream commit fb048cae51 ]

All accesses (both reads and modifications) to
hdev->{accept,reject}_list are protected by hdev lock,
except the ones in hci_conn_request_evt. This can cause a race
condition in the form of a list corruption.
The solution is to protect these lists in hci_conn_request_evt as well.

I was unable to find the exact commit that introduced the issue for the
reject list, I was only able to find it for the accept list.
