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
