x86/efi: Use efi_exit_boot_services()
The eboot code directly calls ExitBootServices. This is inadvisable as the UEFI spec details a complex set of errors, race conditions, and API interactions that the caller of ExitBootServices must get correct. The eboot code attempts allocations after calling ExitBootSerives which is not permitted per the spec. Call the efi_exit_boot_services() helper intead, which handles the allocation scenario properly.
