rt2x00: Style fix for interval defines

From: Alban Browaeys <[email protected]>

Extra parenthesis are not needed in these 2 cases, all other defines in rt2x00 are done without parenthesis so just fixup these 2 cases.

This replaces the "rt2x00: Fix the interval for rfkill and link_tuner." patch which was send recently. Code is the same, only changelog & subject have been changed.
