Li Guifu 45e30390f5 f2fs: fix use-after-free issue ...

[ Upstream commit 99c787cfd2 ]

During umount, f2fs_put_super() unregisters procfs entries after
f2fs_destroy_segment_manager(), it may cause use-after-free
issue when umount races with procfs accessing, fix it by relocating
f2fs_unregister_sysfs().
