[patch] [SCSI] mpt fusion: declare some sizes as unsigned

[Dan Carpenter <dan.carpenter@oracle.com>]

In mptctl_do_mpt_command() we cap the upper bound of .maxSenseBytes but
we don't check for negative values:

	if (karg.maxSenseBytes > MPT_SENSE_BUFFER_SIZE)

I've fixed this by making the type unsigned and I changed the
surrounding types to match as well.
