    libkern: Change idr_replace() return value to align with Linux
    
    The Linux implementation of idr_replace() returns -ENOENT when the `id`
    could not be found.  Change our implementation to do the same to be
    compatible with Linux's.
    
    In addition, Linux's documentation says idr_replace() would return
    -EINVAL if the given pointer was not valid [1].  This should be checked
    in the future.
