efi_loader: efi_handle_protocol set attributes
UEFI spec 2.7 indicates that HandleProtocol can be implemented by calling OpenProtocol with attributes = EFI_OPEN_PROTOCOL_BY_HANDLE_PROTOCOL. Currently we pass attributes = 0 to efi_open_protocol. 0 is not a valid value when calling OpenProtocol. This does not cause any errors yet because our implementation of OpenProtocol is incomplete. We should pass the correct value to enable a fully compliant implementation of OpenProtocol in the future.
