IB/srp: reduce lock coverage of command completion
We only need the lock to cover list and credit manipulations, so push
those into srp_remove_req() and update the call chains.
We reorder the request removal and command completion in
srp_process_rsp() to avoid the SCSI mid-layer sending another command
before we've released our request and added any credits returned by the
target. This prevents us from returning HOST_BUSY unneccesarily.
