net/ice/base: disable Tx pacing option

With the current NVM, after GLOBR, before the first link up event, FW
will return to base driver, the pacing value of 20 percents for some
reason, in the get-link-status AQ command. We then use this value as
the pacing param for the set-mac-info AQ command. As result, we are
limited to 20 percents of the available bandwidth until the first
set-mac-info AQ call after the link up event.
