Since commit 013a07052a1a ("nilfs2: convert metadata aops from writepage
to writepages"), nilfs_mdt_write_folio can't be called from reclaim
context any more. Remove the code keyed of the wbc->for_rename flag,
which is now only set for writing out swap or shmem pages inside the
swap code, but never passed to file systems.
