carl9170: fix spurious restart due to high latency
RX Stress tests of unidirectional bulk traffic with
bitrates of up to 220Mbit/s have revealed that the
fatal-event recovery logic [which was solely triggered
by an out-of-rx-buffer situation] is too aggressive.
The new method now "pings" the device and then
decides - based on the response - whenever
a restart is needed or not.
