9ea2e26aaa ib_srpt: Avoid stopping polling too early for IB completions. 
This resulted in unnecessary complaints about IB completions not being
received in time when removing the ib_srpt kernel module during I/O. Note:
it is still possible that such complaints occur, but much less frequent.

1c358f4222 ib_srpt: Fix "rejected SRP_LOGIN_REQ because creating a new RDMA channel failed" 
Fix two race conditions that could trigger this failure:
- Completion thread not woken up after channel state change.
- Reception of Last WQE event before the channel queue pair was reset.
