Krzysztof Kozlowski ffe6176b7f virtio: store owner from modules with register_virtio_driver() 
Modules registering driver with register_virtio_driver() might forget to
set .owner field.  i2c-virtio.c for example has it missing.  The field
is used by some other kernel parts for reference counting
(try_module_get()), so it is expected that drivers will set it.

Solve the problem by moving this task away from the drivers to the core
virtio code, just like we did for platform_driver in
commit 9447057eaf ("platform_device: use a macro instead of
platform_driver_register").

Fixes: 3cfc883804 ("i2c: virtio: add a virtio i2c frontend driver")
