scsi: core: Add counters for New Media and Power On/Reset UNIT ATTENTIONs
The purpose of the counters is to enable all ULDs attached to a device to
find out that a New Media or/and Power On/Reset Unit Attentions has/have
been set, even if another ULD catches the Unit Attention as response to a
SCSI command.
The ULDs can read the counters and see if the values have changed from the
previous check.
