Merge patch series "virtio: rng: Handle oversized return buffers"

Meet Patel <meet.patel2@arm.com> says:

The virtio-rng test to verify effective handling of oversized return
buffers checks that an (undocumented) error is raised, instead of the
real concern, which is the surrounding buffer integrity following a rng
function call.
Update the test to check that the other contents of a buffer remain
unchanged instead of looking for an error code.
