gpu_plugin: reduce topology scanning for high shared dev count

Browse Source 
For every created device info, a new topology scan is performed in
the filesystem. The shared dev count was implemented so that for each
shared device, a new device info was created, which resulted in the
topology scan happening as many times per Scan-round, as there were
shared devs.

This fixes the issue by making the device info to be shared among the
shared devices.
