[PATCH 5.16 0931/1017] gfs2: Fix gfs2_file_buffered_write endless loop workaround

From: Andreas Gruenbacher agruenba@redhat.com

commit 46f3e0421ccb5474b5c006b0089b9dfd42534bb6 upstream.

Since commit 554c577cee95b, gfs2_file_buffered_write() can accidentally return a truncated iov_iter, which might confuse callers. Fix that.
