scsi: qla2xxx: Do command completion on abort timeout
[ Upstream commit 71c80b75ce8f08c0978ce9a9816b81b5c3ce5e12 ]
On switch, fabric and mgt command timeout, driver send Abort to tell FW to
return the original command. If abort is timeout, then return both Abort
and original command for cleanup.
Fixes: 219d27d7147e0 ("scsi: qla2xxx: Fix race conditions in the code for aborting SCSI commands")
