[PATCH v2 1/3] RedfishPkg/RedfishRestExDxe: fix CPU exception in RedfishRestExDxe

["Nickle Wang" <nicklew@nvidia.com>]

RedfishRestExDxe driver failed to uninstall service binding protocol
when driver binding stop is called. Application drivers may still
use RedfishRestExDxe after it is disconnected in system.
