quota: missing lock in dqcache_shrink_scan()

commit d68aab6b8f572406aa93b45ef6483934dd3b54a6 upstream.

Commit 1ab6c4997e04 (fs: convert fs shrinkers to new scan/count API)
accidentally removed locking from quota shrinker. Fix it -
dqcache_shrink_scan() should use dq_list_lock to protect the
scan on free_dquots list.
