[SCSI] aacraid: use lower snprintf() limit
This is just a cleanup, to silence static checker warnings. It
doesn't change how the code works.
buf[] can either be BUF_SIZE if this is called from sysfs, or it can
be 16 if it's called from aac_get_adapter_info() via
aac_get_serial_number(). We use the smaller limit here.
sizeof(dev->supplement_adapter_info.MfgPcbaSerialNo) is 12 so there
is actually no chance of hitting either limit.
