Introduce the helper function srp_wait_for_queuecommand().
Move the definition of scsi_request_fn_active(). Add a comment
above srp_wait_for_queuecommand() that support for scsi-mq needs
to be added.
This patch does not change any functionality. A second call to
srp_wait_for_queuecommand() will be introduced in the next patch.
