qcacld-3.0: Start P2P_CLI vdev in max supported ch_width

Some APs/P2P-GOs send beacon with 20mhz and assoc resp with 80mhz
and after assoc resp, next beacon also has 80mhz. Connection is
expected to happen in better possible bandwidth(80MHz in this
case).
Start the vdev with max supported ch_width in order to
support this. It'll be downgraded to appropriate ch_width or
the same would be continued based on assoc resp.
