Chao Yu 2f7921d8de ext4: check return value of kstrtoull correctly in reserved_clusters_store ...

commit 1ea1516fbb upstream.

kstrtoull returns 0 on success, however, in reserved_clusters_store we
will return -EINVAL if kstrtoull returns 0, it makes us fail to update
reserved_clusters value through sysfs.
