wifi: iwlwifi: fix byte count table for old devices
commit 586e3cb33ba6890054b95aa0ade0a165890efabd upstream.
For devices handled by iwldvm, bc_table_dword was never set, but I missed
that during the removal thereof. Change the logic to not treat the byte
count table as dwords for devices older than 9000 series to fix that.
