[PATCH] scsi/aacraid: user upper/lower_address() macro to avoid "right shift count >= width of type" warning.

[PATCH] scsi/aacraid: user upper/lower_address() macro to avoid "right shift count >= width of type" warning.

[Sebastian Andrzej Siewior]

Avoids the following warning:
|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]
|    BUG_ON((u32)(address >> 32) != 0L);
|    ^
|drivers/scsi/aacraid/src.c:434:2: warning: right shift count >= width of type [enabled by default]
|   src_writel(dev, MUnit.IQ_H, (address >> 32) & 0xffffffff);
