MdeModulePkg/EsrtFmpDxe: Support multiple devices with 0 HardwareInstance

Browse Source 
Skip error check if HardwareInstance is 0 as this either means that
FmpVersion < 3 and not supported or,
"A zero means the FMP provider is not able to determine a
unique hardware instance number or a hardware instance number
is not needed." per UEFI specification.

As the FmpInstances are merged and HardwareInstance is not used
remove error check in this case.
