drm/i915: Pull unpin map into vma release

A reasonably common operation is to pin the map of the vma alongside the
vma itself for the lifetime of the vma, and so release both pins at the
same time as destroying the vma. It is common enough to pull into the
release function, making that central function more attractive to a
couple of other callsites.

The continual ulterior motive is to sweep over errors on module load
aborting...
