Currently, Hyper-V may be notified of a panic for any die event.

However, this results in false panic notifications for various user
space traps that are die events.

The following commit fixes this by ignoring die events that is not an
oops: 608a973bd52e ("Drivers: hv: vmbus: Only notify Hyper-V for die
events that are oops")

The upstream patch applies cleanly to both focal:linux-azure and
bionic:linux-azure-4.15 as a simple cherry pick.
