[PATCH net v3] net: set static variable an initial value in atl2_probe()

[Mao Wenan]

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.
