scsi: scsi_debug: Divide power on reset UNIT ATTENTION

To distinguish between resets sent by the SCSI mid-level error
handling and newly introduced devices (LUs), this Unit Attention:

   power on, reset, or bus reset occurred [0x29,0x0]

has been subdivided into that UA for the reset case and this new UA:

   power on occurred [0x29,0x1]

for the new device (LU) case. This makes debug a little easier to follow
when it is turned on (e.g. 'echo 0x1 > opts').

Bump driver version number.
