[SCSI] sym2: Mask off opcode from RBC
pm->sg.size is set from the Residual Byte Count register. However, the upper byte of the RBC is the opcode of the instruction that was executing, so we need to mask it off. This fixes some spurious rejects of IGNORE WIDE RESIDUE messages. Signed-off-by: Matthew Wilcox <matthew@wil.cx> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
