Matthew Wilcox (Oracle) a9dc1d3b5b quota: Prevent memory allocation recursion while holding dq_lock 
[ Upstream commit 537e11cdc7 ]

As described in commit 02117b8ae9 ("f2fs: Set GF_NOFS in
read_cache_page_gfp while doing f2fs_quota_read"), we must not enter
filesystem reclaim while holding the dq_lock.  Prevent this more generally
by using memalloc_nofs_save() while holding the lock.
