net: set static variable an initial value in atl2_probe()

Mao Wenan · davem330 · commit 4593403fa516 · 2019-02-23T13:47:13.000-08:00
cards_found is a static variable, but when it enters atl2_probe(),
cards_found is set to zero, the value is not consistent with last probe,
so next behavior is not our expect.
