platform/x86/amd: Fix memory leak in wbrf_record()

In the Linux kernel, the following vulnerability has been resolved:

platform/x86/amd: Fix memory leak in wbrf_record()

The tmp buffer is allocated using kcalloc() but is not freed if
acpi_evaluate_dsm() fails. This causes a memory leak in the error path.

Fix this by explicitly freeing the tmp buffer in the error handling
path of acpi_evaluate_dsm().
