reiserfs: Move quota calls out of write lock
Calls into highlevel quota code cannot happen under the write lock. These calls take dqio_mutex which ranks above write lock. So drop write lock before calling back into quota code. CC: stable@vger.kernel.org # >= 3.0 Signed-off-by: Jan Kara <jack@suse.cz>
