tools/testing/nvdimm: unit test clear-error commands

Browse source 
[ Upstream commit fb2a174835 ]

Validate command parsing in acpi_nfit_ctl for the clear error command.
This tests for a crash condition introduced by commit 4b27db7e26
"acpi, nfit: add support for the _LSI, _LSR, and _LSW label methods".
