scsi: pm8001: Reject non-fatal dump when controller is crashed
pm80xx_get_non_fatal_dump() can be called even after the controller has
entered a fatal error state. In that case the forensic memory contents
are not safe to access for a non-fatal dump request, and attempting to
do so can trigger a call trace.
Check controller_fatal_error before reading the non-fatal dump buffer
and return -EINVAL when the controller is already in a crashed state.
This prevents non-fatal dump collection from running in an invalid
controller state.
