Remove unused function convertCurrentChannelNum(uint8_t)

convertCurrentChannelNum(uint8_t) was deprecated in favor of an
actual working implementation. It was stubbed out for a while to
provide a broken, backwards-compatible interface, but now that all
of those have been removed in favor of the new interface that
actually works: convertCurrentChannelNum(uint8_t, uint8_t), the
old function can be removed.

Tested: Builds without any errors (means the old interface was removed)
