quota: Properly annotate i_dquot arrays with __rcu
Dquots pointed to from i_dquot arrays in inodes are protected by dquot_srcu. Annotate them as such and change .get_dquots callback to return properly annotated pointer to make sparse happy. Fixes: b9ba6f94b238 ("quota: remove dqptr_sem") Signed-off-by: Jan Kara <jack@suse.cz>
