[RFC 06/10] nl80211_driver: add support for P2P device in adding and removing interface

[Arend van Spriel]

From: David Spinadel <david.spinadel at intel.com>

Don't try to assign ifindex for P2P device interface and
check that the ifindex is valid before trying to remove it.

Don't try to set TX rates for P2P device interface since it's
not a network device.
