[bsc_hack] Sanity check for the GSM1800 nanoBTS

The GSM1800 requires us to use channels between 512-885. When
failing to provide such a channel the OML layer will fail and
no RSL connection will be opened.

Add a sanity check before creating the gsm_network and fail
when the channels are not within the allowed range.

Assume no one is operating a BS11 in the 1800 spectrum.
