drm/ttm: add bit flag TTM_OPT_FLAG_FORCE_ALLOC
set TTM_OPT_FLAG_FORCE_ALLOC when we are servicing for page fault routine. for ttm_mem_global_reserve if in page fault routine, allow the gtt pages reservation always. because page fault routing already grabbed system memory and the allowance of this exception is harmless. Otherwise, it will trigger OOM killer. will be used later. v2: set the FORCE_ALLOC always v3: minor refine Signed-off-by: Roger He <Hongbo.He@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
