aic79xx.c:

Use the special LUNLEN_SINGLE_LEVEL constant for
	post Rev A4 hardware for single byte luns.  Without
	this change, Rev B hardware would place the single
	byte of lun data in byte 0 of the lun structure when
	it should be in byte 1.  Since there are few if any
	devices on the market that support multiple luns in
	target mode, the corrupted lun field (which was only
	corrupted for non-zero luns) wasn't hurting us.
