wifi: iwlwifi: uninitialized variable in iwl_acpi_get_ppag_table()

This is an error path and Smatch complains that "tbl_rev" is uninitialized
on this path.  All the other functions follow this same patter where they
set the error code and goto out_free so that's probably what was intended
here as well.
