MDEV-28923 atomic.rename_table occasionally fails

fil_name_process(): If the recovery of a tablespace was deferred,
do invoke fil_ibd_load() even though the name in recv_spaces is
not changing. This allows us to recover from a situation where
there are many FILE_RENAME records, renaming a tablespace back
and forth, and a FILE_MODIFY record that had been written by
fil_names_clear().
