[Intel-gfx] [PATCH v6 3/6] drm/i915: Don't pin the object pages during pending vma binds

[Thomas Hellström]

A pin-count is already held by vma->pages so taking an additional pin
during async binds is not necessary.

When we introduce async unbinding we have other means of keeping the
object pages alive.
