mac80211: support runtime interface type changes
Add support to mac80211 for changing the interface type even when the interface is UP, if the driver supports it. To achieve this * add a new driver callback for switching, * split some of the interface up/down code out into new functions (do_open/do_stop), and * maintain an own __SDATA_RUNNING bit that will not be set during interface type, so that any other code doesn't use the interface.
