xfs: refactor xfs_rtbitmap_blockcount
Rename the existing xfs_rtbitmap_blockcount to
xfs_rtbitmap_blockcount_len and add a new xfs_rtbitmap_blockcount wrapper
around it that takes the number of extents from the mount structure.
This will simplify the move to per-rtgroup bitmaps as those will need to
pass in the number of extents per rtgroup instead.
