nl80211: Disable 11b rates for P2P (additional cases)

Some drivers (like mac80211) do not accept changing the TX bitrate mask
before the network interface is up. Thus, calling
nl80211_disable_11b_rates() before the interface is up fails, and the
P2P network interface continues to use invalid bitrates.

To fix this call nl80211_disable_11b_rates() immediately after the
interface is brought up (and also after rfkill is unblocked).
