vty: reassign: add missing check for valid target lchan

Make sure that the target lchan has been initialized before attempting
to reassign.

I ran into this in the VAMOS tests, forgetting to set the BTS_FEAT_VAMOS
in osmo-bts-omldummy: the vty command from ttcn attempts to reassign to
a non-initialized lchan, and aborts osmo-bsc.
