qcacmn: For p2p scan skip DFS channels only

In the current implementation, when ini gSkipDfsChannelInP2pSearch
is set then DFS channels are skipped for p2p scan but side-effect is
passive and indoor channels are also skipped. This is because api
wlan_reg_is_dfs_ch() returns true for passive, indoor and DFS channels.

To fix this, use api wlan_reg_chan_has_dfs_attribute() instead of
wlan_reg_is_dfs_ch() for explicitly getting DFS (radar) channels only.
