fbdev_set_par is called when fbcon is taking over control.
In the past frontbuffer was being invalidated on
set_to_gtt_domain, but it moved to set_domain fixing that case,
but left this behind.
Commit that changed this fixing set_domain case was:
commit 031b698a77a70a6c394568034437b5486a44e868

drm/i915: Unconditionally do fb tracking invalidate in set_domain
Since we are also invalidating in other fbdev cases this one
was masked here. At least until now that I found this corner
case: On boot with plymouth doing a splash screen
when returning to the console frontbuffer wans't being invalidated
causing missed screen updates with PSR enabled.
So this patch fixes this issue.
v2: Make invalidate directly and unconditionally and
fix commit message indicating the set_domain fix
as pointed out by Daniel.
