BZ 4037:
Install EFI_DISCOVER_PROTOCOL on each network interface.
This fixes the issue that causes the high-level Redfish driver
on the network interface is stopped when:
1. EFI_DISCOVER_PROTOCOL is reinstalled on a new-found network
interface, or
2. EFI_DISCOVER_PROTOCOL is stopped on the network interface
other than the one which is used to communicate with Redfish
service.
