scsi: smartpqi: Fix RAID map race condition
Correct a rare stale RAID map access when performing AIO during a RAID
configuration change.
A race condition in the driver could cause it to access a stale RAID map
when a logical volume is reconfigured.
Modify the driver logic to invalidate a RAID map very early when a RAID
configuration change is detected and only switch to a new RAID map after
the driver detects that the RAID map has changed.
