Differentiate depleted and unset multipath quota

NetworkPolicyManagerInternalImpl#getSubscriptionOpportunisticQuota
would return 0 both for unset and depleted quota, which cannot be
interpreted properly by MultipathPolicyTracker (the only caller),
to use a fallback policy.

Return OPPORTUNISTIC_QUOTA_UNKNOWN (-1) instead for unknown quota.
