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

[David Francis <David.Francis@amd.com>]

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.
