Subject: nilfs2: remove wbc->for_reclaim handling
Date: Fri, 16 May 2025 21:31:13 +0900

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_reclaim flag,
which is now only set for writing out swap or shmem pages inside the swap
code, but never passed to file systems.
