scsi: smartpqi: correct volume status
[ Upstream commit 7ff44499bafbd376115f0bb6b578d980f56ee13b ]
- fix race condition when a unit is deleted after an RLL,
and before we have gotten the LV_STATUS page of the unit.
- In this case we will get a standard inquiry, rather than
the desired page. This will result in a unit presented
which no longer exists.
- If we ask for LV_STATUS, insure we get LV_STATUS
