quota: Properly annotate i_dquot arrays with __rcu

Browse source 
[ Upstream commit ccb49011bb2ebfd66164dbf68c5bff48917bb5ef ]

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.
