drm/amdgpu: use correct gfp_t for job allocation

Browse source

For job allocation in GPU reset and page fault handling we must use
GFP_ATOMIC to guarantee that we don't cycle back and depend on a
dma_fence submission for the memory allocation.

Add gfp_flags argument to amdgpu_job_alloc() and expose the
gfp_flags of IB pools with amdgpu_ib_pool_gfp_flags() so that
we can use different flags when allocating jobs.
