Subject: [PATCH] scsi: esp_scsi: Always clear msg_out_len after MESSAGE OUT
phase
References: bsc#1077989
Git-commit: d60e9eec95d2e81253eaf3c39ac8baf4830d0472
Patch-mainline: v4.14-rc1
After sending a message, always clear esp->msg_out_len. Otherwise,
eh_abort_handler may subsequently fail to send an ABORT TASK SET
message.
