[PATCH 1/3] plugin/amdgpu: Add plugin to inventory even if there are no vmas

The amdgpu plugin is added to the plugin inventory as the first
vma map is dumped. But it's completely possible for a process to
have driver files open but no vma maps. In this case, we still
will need the plugin on restore.

Add the plugin to the inventory whenever a device file is dumped.
