fix(device_info_plus): #2957 replaces throwing exception with returning default values

[miquelbeltran]

Description

As discussed in #2957 seems that some Windows VMs will return 0 when asked for physical device memory, which causes the plugin to throw an exception.

The main issue is that 3rd party devs using this plugin in their packages may not properly catch exceptions.

This PR replaces these types of exception errors with returning default values, to avoid uncaught exceptions.
