drm/shmem: Cleanup drm_gem_shmem_create_with_handle()
Once we create the handle, the handle owns the reference. Currently
nothing was doing anything with the shmem ptr after the handle was
created, but let's change drm_gem_shmem_create_with_handle() to not
return the pointer, so-as to not encourage problematic use of this
function in the future. As a bonus, it makes the code a bit cleaner.
