Subject: [PATCH] scsi: ibmvscsis: Fix write_pending failure path
References: bsc#1077989
Git-commit: 88e65389fce1f68ba6d13ae2fc0f8d7e5c338c52
Patch-mainline: v4.14-rc4
For write_pending if the queue is down or client failed then return -EIO
so that LIO can properly process the completed command. Prior we
returned 0 since LIO could not handle it properly. Now with commit
fa7e25cf13a6 ("target: Fix unknown fabric callback queue-full errors")
that patch addresses LIO's ability to handle things right.
