[PULL 06/29] scsi: allow user to set werror as report

Subject: [PULL 06/29] scsi: allow user to set werror as report
Date: Fri, 26 Feb 2021 09:05:03 +0100

From: Zihao Chang <changzihao1@huawei.com>

'enospc' is the default for -drive, but qemu allows user to set
drive option werror. If werror of scsi-generic is set to 'report'
by user, qemu will not allow vm to start.

This patch allow user to set werror as 'report' for scsi-generic.
