[PATCH] scsi: allow user to set werror as report

[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.
