scsi: lpfc: Fix locking for lpfc_sli_iocbq_lookup()

commit d5a943bc6360cd3f7ec2a807869197e73fe37691 upstream.

The rules changed for lpfc_sli_iocbq_lookup() vs locking. Prior, the
routine properly took out the lock. In newly refactored code, the locks
must be held when calling the routine.

Fix lpfc_sli_process_sol_iocb() to take the locks before calling the
routine.

Fix lpfc_sli_handle_fast_ring_event() to not release the locks to call the
routine.
