Issue was raised in [1], attempt to fix this by holding PM ref when GT
TLB invalidations are in flight. An alternative solution could be hold a
PM ref when any H2G are inflight which expect a G2H.

Including two patches from [2] as they a prerequisite for this fix.

[2] https://patchwork.freedesktop.org/series/135809/

v2: Fix CI failure
v3: send correct patches
