4.17-stable review patch. If anyone has any objections, please let me know.

From: Chao Yu <yuchao0@xxxxxxxxxx>
[ Upstream commit c22aecd75919511abea872b201751e0be1add898 ]
dquot_initialize() can fail due to any exception inside quota subsystem,
f2fs needs to be aware of it, and return correct return value to caller.
