Kernel/VirtIO: Improve error handling during device initialization

Browse source 
Rename the initialize method to initialize_virtio_resources so it's
clear what this method is intended for.

To ensure healthier device initialization, we could also return the type
of ErrorOr<void> from this method, so in all overriden instances and in
the original method code, we could leverage TRY() pattern which also
does simplify the code a bit.
