Chris Wilson 057f803ff1 drm/i915: Reorder phys backing storage release 
In commit a4f5ea64f0 ("drm/i915: Refactor object page API"), I
reordered the object->pages teardown to be more friendly wrt to a
separate obj->mm.lock. However, I overlooked the phys object and left it
with a dangling use-after-free of its phys_handle. Move the allocation
of the phys handle to get_pages and it release to put_pages to prevent
the invalid access and to improve symmetry.

v2: Add commentary about always aligning to page size.

Testcase: igt/drv_selftest/objects
