ACPI: NFIT: Use cleanup.h helpers instead of devm_*()

Browse source 
The new cleanup.h facilities that arrived in v6.5-rc1 can replace the
the usage of devm semantics in acpi_nfit_init_interleave_set(). That
routine appears to only be using devm to avoid goto statements. The
new __free() annotation at variable declaration time can achieve the same
effect more efficiently.

There is no end user visible side effects of this patch, I was
motivated to send this cleanup to practice using the new helpers.
