If the parent up/down task was queued then sync with it before returning from
the vap ioctl. This means that the parent interface should hopefully be up
before we return to userland, it does not depend on the parent init succeeding,
just that it was run.
This fixes wpa_supplicant with ndis and USB where the parent interfaces can be
slow to init.
