gfs2: Fix gfs2_file_buffered_write endless loop workaround

Browse Source 
[ Upstream commit 46f3e0421ccb5474b5c006b0089b9dfd42534bb6 ]

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

Fixes: 554c577cee95b ("gfs2: Prevent endless loops in gfs2_file_buffered_write")
