If connection preparation fails for MLO connections, then the
interface is completely reset to non-MLD. In this case, we must
not keep the station since it's related to the link of the vif
being removed. Delete an existing station. Any "new_sta" is
already being removed, so that doesn't need changes.
This fixes a use-after-free/double-free in debugfs if that's
enabled, because a vif going from MLD (and to MLD, but that's
not relevant here) recreates its entire debugfs.
