Simple infrastructure changes for supporting multiple virtual interfaces (multiple VIFs). It is still not possible to add new VIFs so the only VIF belongs to the main interface. Main changes: 1. Add MAC ID(mid) argument to wmi_send and wmi_call to allow invoking WMI commands on different VIFs. 2. Similarly, in WMI event handler look at the mid reported by FW and extract VIF structure (currently only for main interface). All WMI event handlers operate on wil6210_vif structure so they know on which VIF they were called. 3. Trivial changes to use wil6210_vif structure and MID throughout the code. 4. Various changes to logging to report MID. More complete multiple VIFs support will be added gradually in next patches.
