iwlwifi: fix iwl_uefi_get_uats_table() if not compiled with ACPI

Apply a temporary fix to FreeBSD only to allow AX101 to proceed
further. While this fix results in a debug error message if
firmware debugging is on we currently take this for the version
we have. A proper fix will eventually show up in future versions
of iwlwifi.
