efi/libstub: Use efi_exit_boot_services() in FDT
The FDT 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 FDT code does not handle EFI_INVALID_PARAMETER as required by the spec, which causes intermittent boot failures on the Qualcomm Technologies QDF2432. Call the efi_exit_boot_services() helper intead, which handles the EFI_INVALID_PARAMETER scenario properly.
