Kernel: Store device class name as member of VirtIO devices

Browse source 
This ensures we dont try to hold the PCI Access mutex under IRQ when
printing VirtIO debug logs (which is not allowed and results in an
assertion). This is also relatively free, as it requires no allocations
(we're just storing a pointer to the rodata section).
