[RFC PATCH 05/10] vdpa: remove WARN_ON() in the get/set_config callbacks

[Stefano Garzarella]

vdpa_get_config() and vdpa_set_config() now check parameters before
calling callbacks, so we can remove these warnings.

Maybe we can skip this patch and leave the WARN_ONs in place.
What do you recommend?
