Certain HCA types (e.g. Connect-IB) and certain configurations (e.g. ConnectX VF) support fast registration but not FMR. Hence add fast registration support. In function srp_rport_reconnect(), move the the srp_finish_req() loop from after to before the srp_create_target_ib() call. This is needed to avoid that srp_finish_req() tries to queue any invalidation requests for rkeys associated with the old queue pair on the newly allocated queue pair. Invoking srp_finish_req() before the queue pair has been reallocated is safe since srp_claim_req() handles completions correctly that arrive after srp_finish_req() has been invoked.
