xfs: fold xfs_bmbt_init_common into xfs_bmbt_init_cursor

Browse source

Make the levels initialization in xfs_bmbt_init_cursor conditional
and merge the two helpers.

This requires the fakeroot case to now pass a -1 whichfork directly
into xfs_bmbt_init_cursor, and some special casing for that, but
at least this scheme to deal with the fake btree root is handled and
documented in once place now.
