drm/amdgpu: skip printing vram_lost if needed

Browse Source 
The vm lost status can only be obtained after a GPU reset occurs, but
sometimes a dev core dump can be happened before GPU reset. So a new
argument is added to tell the dev core dump implementation whether to
skip printing the vram_lost status in the dump.
And this patch is also trying to decouple the core dump function from
the GPU reset function, by replacing the argument amdgpu_reset_context
with amdgpu_job to specify the context for core dump.

V2: Inform user if VRAM lost check is skipped so users don't assume
VRAM wasn't lost (Alex)
