"freecount" in the xfs_inobt_rec is unsigned, so xfs_db should print it as such. Not doing so tickles a bug in getbitval() where we try to handle sign extension for signed fields and fail badly on big endian machines, causing us to incorrectly report negative numbers when printing structures even when the number is nowhere near the signed maximum value. So this fix works around that bug by properly marking this field as unsigned, because I have yet to convince myself of the proper fix for the underlying bug.
