bcachefs: Fix swallowing of data in buffered write path In __bch2_buffered_write, if we fail to write to an entire !uptodate folio, we have to back out the write, bail out and retry. But we were missing an iov_iter_revert() call, so the data written to the folio was lost and the rest of the write shifted to the wrong offset.
