[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.
