[U-Boot] [PATCH 2/2] efi_selftest: fix variables test for GetNextVariableName()

[AKASHI Takahiro]

There is a bug in efi variables test.
Fix it with some cosmetic improvements.

Please note that efi variables test still fails at QueryVariableInfo()
and GetVariable(), but this is not due to a change in this patch.
