Shift rcu_read_{,un}lock() inside fast_dput()

Browse source

Shrink rcu_read_lock() scopes surrounding fast_dput() calls.
Both callers are immediately preceded and followed by
rcu_read_lock()/rcu_read_unlock() resp.  Shrink that down
into fast_dput() itself; in case when fast_dput() ends up
grabbing ->d_lock, we can pull rcu_read_unlock() up to
right after spin_lock().
