nl80211: Disable 11b rates on configuring P2P interface

Right now 11b rates are masked out while creating a P2P interface,
but this is always failing as the interface is down. Most drivers
allow to configure rates only when the interface is UP and running.
So let us disable 11b rates when interface type is changed into a
P2P type and it is UP and running.
