skd: Submit requests to firmware before triggering the doorbell ...
commit 5fbd545cd3fd311ea1d6e8be4cedddd0ee5684c7 upstream.
Ensure that the members of struct skd_msg_buf have been transferred
to the PCIe adapter before the doorbell is triggered. This patch
avoids that I/O fails sporadically and that the following error
message is reported:
(skd0:STM000196603:[0000:00:09.0]): Completion mismatch comp_id=0x0000 skreq=0x0400 new=0x0000
