Andrew Goodbody 5753dc3f65 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.
