qcacld-3.0: Append secondary wlan number to LOCAL_MOD_NAME

For dual wlan chip, local module name will be same once TARGET_MULTI_WLAN
is set to true. For example, for dual HST, two wlan driver modules will
be created. If TARGET_MULTI_WLAN is true, two modules qca6390 will be
created.

So append number to secondary module. One is qca6390, the other is
qca6390_2.
