[PATCH 3/3] uefirtmisc: add checking the EFI_UNSUPPORTED return code

[Ivan Hu]

The UEFI spec 2.8(Matis 1961) adds EFI_UNSUPPORTED as a return code to most
UEFI runtime services for those embeded devices such as specified by the
ARM EBBR specification which are impractical or impossible to implement
in such a way that they can be used at runtime.

Add checking the EFI_UNSUPPORTED return code and skip the test for those
unsupported runtime services.
