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.

v1->v2: change the subject from "net: drop pointless static qualifier in atl2_probe()"
to "net: set static variable an initial value in atl2_probe()";
keep 'static' for variable cards_found.
v2->v3: change patch description, and send patch to netdev mail list.
