Fix ONS to only return opportunistic subs
As part of the auto-data-switch, it became possible for
the ONS to accidentally return a preferred data sub-ID
that was not opportunistic, which broke the contract of
TelephonyManager#getPreferredOpportunisticDataSubscription.
Since there's no reason for ONS to mess with non-opportunistic
subs, it's safe to just have it not find one in the case that
the preferred sub is not an opportunistic sub.
