Jeffrey Hugo ed9cc156c4 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.
