Remove unnecessary channel list filtering

Operating channel is always set even without an STA connected. Remove
channel list filtering based on that.

Channel list is filtered in the p2p_connect and p2p_invite path based
on force_freq which is essentially the operating channel for STA

This patch helps fix WifiDirect b/w two android devices for SCC while at
the same time keeping channel compliance with WFD dongle
