[SCSI] aacraid: suppress two GCC warnings
Building src.o for a 32 bit system triggers two GCC warnings:
drivers/scsi/aacraid/src.c: In function ‘aac_src_deliver_message’:
drivers/scsi/aacraid/src.c:410:3: warning: right shift count >= width of type [enabled by default]
drivers/scsi/aacraid/src.c:434:2: warning: right shift count >= width of type [enabled by default]
These warnings are caused by a right shift of 32. Use upper_32_bits() to
suppress them.
