rsl: NACK Chan Activation for lchans on disabled TS

A broken BSC could send a Chan Activation on a TS which has not yet been
enabled (or even configured). This is the case with our TTCN3 tests,
where OML side is currently handled in parallel by an osmo-bsc while
TTCN3 takes care of the RSL side. This can actually be seen as a
malfunctioning BSC, but it was spotted that given this sequence of
events osmo-bts can crash (see ticket below).

Hence, let's NACK any attempt from a BSC to activate an lchan on a
disabled TS.
