drm/amdgpu: Remove a few holes from struct amdgpu_ctx

Re-order the struct members a bit to avoid some holes:

/* size: 408, cachelines: 7, members: 15 */
/* sum members: 393, holes: 4, sum holes: 15 */
/* last cacheline: 24 bytes */

/* size: 400, cachelines: 7, members: 15 */
/* sum members: 393, holes: 1, sum holes: 7 */
/* last cacheline: 16 bytes */

While doing so we notice a duplicate but will address than in the
following patch.
