P2P: Optimize default case for own freq preference setting

There is no need to use wpas_p2p_num_unused_channels() here in the
default configuration of p2p_ignore_sahred_freq=0, so re-order the
conditions to skip that operation. This is a bit more efficient and the
debug log is also a bit cleaner in the default case.
