Subject: [PATCH -next] f2fs: fix error return code in init_f2fs_fs()

From: Wei Yongjun <yongjun_wei@...ndmicro.com.cn>

Fix to return -ENOMEM in the kset create and add error handling
case instead of 0, as done elsewhere in this function.

Introduced by commit b59d0bae6ca30c496f298881616258f9cde0d9c6.
(f2fs: add sysfs support for controlling the gc_thread)
