wifi: mac80211: remove debugfs dir for virtual monitor
Don't call ieee80211_debugfs_recreate_netdev() for virtual monitor
interface when deleting it.
The virtual monitor interface shouldn't have debugfs entries and trying
to update them will *create* them on deletion.
And when the virtual monitor interface is created/destroyed multiple
times we'll get warnings about debugfs name conflicts.
