[XFS] make btree root in inode support generic
The bmap btree is rooted in the inode and not in a disk block. Make the support for this feature more generic by adding a btree flag to for this feature instead of relying on the XFS_BTNUM_BMAP btnum check. Also clean up xfs_btree_get_block where this new flag is used. Based upon a patch from Dave Chinner.
