qcacld-3.0: Move p2p work around to change_iface

hdd_change_adapter_mode() contains a work around for an issue with
userspace requesting station mode on a p2p adapter, expecting the wlan
driver to instead change the adapter to p2p-device mode. Hoist this work
around to the caller, __wlan_hdd_cfg80211_change_iface, so the rest of
the code doesn't need to be aware of it.
