method: \_SB_.NVDR.N000._NIH should return a buffer of 64 bytes, but instead returned 4 bytes.

[liupeng17]

On a platform with NVDIMM deivices, fwts reports the errors ``method: _SB_.NVDR.N000._NIH should return a buffer of 64 bytes, but instead returned 4 bytes.'' But according to ACPI spec definition of _NIH, the length of _NIH output buffer is 4 bytes instead of 64 bytes.

Seems fwts/src/lib/src/fwts_acpi_object_eval.c should be changed:
