Jan Kara c12efda47d quota: Fix rcu annotations of inode dquot pointers ...

[ Upstream commit 179b8c97eb ]

Dquot pointers in i_dquot array in the inode are protected by
dquot_srcu. Annotate the array pointers with __rcu, perform the locked
dereferences with srcu_dereference_check() instead of plain reads, and
set the array elements with rcu_assign_pointer().
