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

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

From: Wang Shilong <wshilong@ddn.com>

commit 182a79e0c17147d2c2d3990a9a7b6b58a1561c7a upstream.

We return most failure of dquota_initialize() except
inode evict, this could make a bit sense, for example
we allow file removal even quota files are broken?

But it dosen't make sense to allow setting project
if quota files etc are broken.
