[SCSI] qla2xxx: Correctly read sfp single byte mailbox register.
When reading a single byte using the READ SFP mailbox command, the
single byte of data is returned in MB[1] and not MB[8].
The reason that MB[8] was being used is that the spec was unclear
as it evolved over time; and we have not needed to read a single
byte until recently.
