LRWD: masking bugreport triggers

If watchdog experiences another network connection failure after
restarting wifi, then assume that the restart did not fix the problem
and therefore don't trigger a bugreport when wifi finally connects.

Bug: 77655949
Test: compile, unit tests
Manual test:
Flash build
create a soft AP on another device
Connect to that soft AP
Change the password of the soft AP
Wait for watchdog to trigger
Connect to Google Guest
Do "adb shell dumpsys wifi" and verify the following:
1. mWifiLogProto.numLastResortWatchdogTriggers=1
2. mWifiLogProto.numLastResortWatchdogSuccesses=0
