Fix crash with ath10k for PCI bus type. The crash happens
when the DUT acts as an AP mode and an external client gets
connected. qca-rfs as of now assumes that all the ath10k chipsets
are registered as platform device driver (platform bus type), fix
this by fetching the 'bus->name' and obtain the wifi interrupt
accordingly based on whether its a 'platform' bus type (or) PCI
bus type.

It is a normal case that smp_affinity of an IRQ is not specified, when hit
this condition, we should not print messages to the console.
and in some cases, especially that there are many wifi interface(which can be
created 48), if all these interfaces are created or destroyed at almost the
same time, too many printk will cause RCU stall.

Xbox shared one MAC address for wired and wireless interfaces. Because
SSDK uses static FDB entries to implement RFS feature, it caused packets
were dropped by switch.

In this change, once QRFS finds an MAC address moved from one interface
to another interface, the static FDB entry will be deleted immediately.
