drm/amdgpu: Skip the coredump collection on reset during driver reload
In passthrough environment, the driver triggers the mode-1 reset on
reload. The reset causes the core dump collection which is delayed task
and prevents driver from unloading until it is completed. Since we do
not need to collect data on "reset on reload" case, we can skip core
dump collection.
v2: Use the same flag to avoid calling amdgpu_reset_reg_dumps as well.
