ACPI: pfr_telemetry: use ACPI_FREE() to free acpi_object
[ Upstream commit 0f2aa7fc2a9aee05bafb965d5b1638d3e74b4c61 ]
acpi_evaluate_dsm_typed()/acpi_evaluate_dsm() should be coupled
with ACPI_FREE() to free the ACPI memory, because we need to
track the allocation of acpi_object when ACPI_DBG_TRACK_ALLOCATIONS
enabled, so use ACPI_FREE() instead of kfree().
