nrUE NAS: minor changes in get_allowed_nssai()

Browse Source 
This function was very wrong, now it's just wrong.
(It does not sanitize the input properly. Some bad input may have
unexpected effects on the nrUE.)

It needs a serious rewrite.

I just wanted to "fix" it so that it processes correctly some
correct input data.
