f2fs: fix double free of f2fs_sb_info
kill_f2fs_super() is called even if f2fs_fill_super() fails.
f2fs_fill_super() frees the struct f2fs_sb_info, so it must set
sb->s_fs_info to NULL to prevent it from being freed again.
Fixes: 275dca4630c1 ("f2fs: move release of block devices to after kill_block_super()")
