When the smaller id is not found, idr_replace() returns -ENOENT.
But when the id is bigger enough, idr_replace() returns -EINVAL,
actually there is no difference between these two kinds of ids.
These are all unallocated id, the return values of the idr_replace()
for these ids should be the same: -ENOENT.
