RedfishPkg: fix multiple SMBIOS type 42 version issue

RedfishHostInterfaceDxe does not close protocol notify event in
event callback function. This could cause multiple version of
type 42 records issue if the protocol is installed more than once.
Close the event in callback function so we only create one type 42
record.
