efi_loader: Add exit support
Some times you may want to exit an EFI payload again, for example
to default boot into a PXE installation and decide that you would
rather want to boot from the local disk instead.
This patch adds exit functionality to the EFI implementation, allowing
EFI payloads to exit.
