drm/i915/gem: Unify user object creation (v3)
Instead of hand-rolling the same three calls in each function, pull them
into an i915_gem_object_create_user helper. Apart from re-ordering of
the placements array ENOMEM check, there should be no functional change.
v2 (Matthew Auld):
- Add the call to i915_gem_flush_free_objects() from
i915_gem_dumb_create() in a separate patch
- Move i915_gem_object_alloc() below the simple error checks
v3 (Matthew Auld):
- Add __ to i915_gem_object_create_user and kerneldoc which warns the
caller that it's not validating anything.
