network_WiFi_Reset: test whether Wifi device can recover from 'reset'

Many Wifi adapters use a reset mechanism to recover from firmware errors
or crashes. These typically happen automatically, but for Marvell
(mwifiex) devices, they can also be triggered via debugfs. Let's test to
make sure that we can recover our Wifi link after a few resets.

At the moment, we don't use this reset interface explicitly, but this is
still a good proxy for testing some aspects of the firmware
crash/recovery behavior.

BUG=b:37946775
TEST=netowrk_WiFi_Reset; see TestNA on Intel devices, and see proper
     reset tests on various Marvell-based boards (snow, veyron_jaq,
     kevin, etc.)
