[media] dvb-frontends/drxk: don't log errors on unsupported operation mode
When fe_ops.read_status is called and no channel is tuned (yet), the subsequent calls to get_lock_status() causes the kernel log to be filled with drxk: Error -22 on get_lock_status which either means a NULL pointer was passed for the p_lock_status var, or neither QAM nor OFDM/DVBT operation mode are active. Instead of filling the kernel log in the latter case, print out a message to the debug level and return 0 (this isn't used in the calling drxk_get_stats() anyway).
