Azure: Limit Hyperv error messages

[Tim Gardner]

SRU Justification

[Impact]

Hyperv can emit copious numbers of error messages "Unable to send packet via vmbus".

[Test Plan]

Microsoft tested, patches are upstream.

[Regression Potential]

Commit 19b5e6659eaf537ebeac90ae30c7df0296fe5ab9 ('drm/hyperv: Don't overwrite dirt_needed value set by host') fixes a race condition that could have unforeseen side effects.

[Other Info]

SF: #00359893

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-azure/5.15.0-1040.47 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
