Don't drop OML links for Get Attributes NACK

Previously any OML NACK message will result in BSC dropping OML link to
BTS which makes it impossible to use optional OML messages which might
be unsupported by BTS. Fix this for 3GPP TS 52.021 §8.11.1 Get
Attributes message. Also, log human-readable NACK name to see what
exactly causing OML link drop.
