In commit 450cede7f380 ("drm/i915/gem: Fix the mman selftest") we fixed up the mman selftest to allocate user buffers via smem only if we have lmem, otherwise it uses internal buffers. As the commit message asserts, we should only be using buffers that userland should be able to create. Internal buffers are not intended to be used by userland. Instead, fix the code to always create buffers from smem. In the case of integrated, this will create them from the shmem non-ttm backend, which is fine. This also fixes up the code to allow conversion of internal backend to ttm without breaking this test.
