Eliminate swap macro related unused variable compilation warnings

Unfortunately, commit c530ebb5 did not
the check for ABI_VIDEODRV_VERSION where the swap macros are actually
used in the code. Checking for ABI_VIDEODRV_VERSION suppresses unused
variable compilation warnings for newer versions of the X Server.
