efi_loader: Prevent dereference of uninitialised variable
If phandler is returned as NULL from efi_search_protocol then
protocol_interface is never assigned to. Instead return
EFI_UNSUPPORTED as per the spec.
This issue found by Smatch.
Also eliminate the use of the variable protocol_interface as it is not
needed.
