Check boot mode to validate parameter HostNumber

Identify boot mode of the system using an existing dbus service.
Boot mode for Single Node [2P-Default] is 0 and it is
1 for Multi-Node [2x1P].

Check the URL for resource bios_active and parameter HostNumber.
If the boot mode is Multi-Node [2x1P] and HostNumber is 0,
return an error.
0 is not a valid parameter HostNumber value for the resource
bios_active on Multi-Node [2x1P] systems.

Tested:
Verified on Multi-Node [2x1P] and Single Node [2P-Default] systems.
