[PATCH 4.14 060/246] f2fs: fix to detect failure of dquot_initialize

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

------------------

From: Chao Yu <redacted>

[ 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.
