f2fs: fix to return 0 if err == -ENOENT in f2fs_readdir
Commit 57b62d29ad5b384775974973087d47755a8c6fcc ("f2fs: fix to report error in f2fs_readdir") causes f2fs_readdir to return -ENOENT when get_lock_data_page returns -ENOENT. However, the original logic is to continue when get_lock_data_page returns -ENOENT, but it forgets to reset err to 0. This will cause getdents64 incorretly return -ENOENT when lastdirent is NULL in getdents64. This will lead to a wrong return value for syscall caller.
