iwlwifi: send calibration results as HUGE commands

This patch saves memory by reducing the size of the entry in the txq. It
was 640 because of the calibration commands. Calibration commands are now
sent as HUGE commands (using the extra 1024 bytes at the end of the command
txq), hence, there is no need for 640 in every entry any more.
