qlcnic: fix mac address mgmt

We first add mac address in driver local list and then send command to
fw to add same. There are checks in driver to ensure send command doesn't fail
before adding mac address in local list.

But instead fix should be:
Add mac address in fw and if it succeeds, add it in driver local list.
