ApfFilter maintains separate counters for each reason why a packet was
passed or dropped by the filter logic.
There's also a total which should match the individual counters,
*unless* the APF interpreter aborted execution early due to an illegal
instruction or an out-of-bounds access.
Test: both on APFv2 and APFv4-capable device:
runtest -x tests/net/java/android/net/ip/IpClientTest.java
runtest -x tests/net/java/android/net/apf/ApfTest.java
