xfs: simplify mappedbno handling in xfs_da_{get,read}_buf
Shortcut the creation of xfs_bmbt_irec and xfs_buf_map for the case
where the callers passed an already mapped xfs_daddr_t. This is in
preparation for splitting these cases out entirely later. Also reject
the mappedbno case for xfs_da_reada_buf as no callers currently uses
it and it will be removed soon.
