xfs: split the per-btree union in struct xfs_btree_cur
Split up the union that encodes btree-specific fields in struct
xfs_btree_cur. Most fields in there are specific to the btree type
encoded in xfs_btree_ops.type, and we can use the obviously named union
for that. But one field is specific to the bmapbt and two are shared by
the refcount and rtrefcountbt. Move those to a separate union to make
the usage clear and not need a separate struct for the refcount-related
fields.
This will also make unnecessary some very awkward btree cursor
refc/rtrefc switching logic in the rtrefcount patchset.
