ipacm: fix the v6-offload issue on Android

Remove the check on how many ipv6 addresses
are received from modem interface, fix the
client prefix comparison logic which contradicts
with MDM requirement to only offload
tethered-clients who has same prefix as
modem interface.

Test: as follows
    - built
    - flashed
    - booted
    - started tethering and watched for packets via:
      "adb shell tcpdump -n -i wlan0 -l"
