Subject: scsi: qla2xxx: Fix I/O errors during LIP reset tests
Patch-mainline: v5.10-rc1
Git-commit: a35f87bdcc0615c5a3a695d13dd1ccf827826368
References: bsc#1171688 bsc#1174003
In .fcp_io(), returning ENODEV as soon as remote port delete has started
can cause I/O errors. Fix this by returning EBUSY until the remote port
delete finishes.
