Fill the linkproperties for INACTIVE PDN

Issue Description:
The IwlanDataService reports the empty LinkProperties for the PDN marked as UNKNOWN or INACTIVE. But according to framework design, Iwlan should not report the empty IP or interface name during the life cycle of PDN.

Fill out the parameters of PDN which is still alive but in INACTIVE
state for the correct behavior.

Bug: 233958181
Test: VoWifi works
      Iwlan reports INACTIVE PDN with full parameters.
