[1/3] net/mlx5: fix compilation issue with missing DevX event

  If there is no support for DevX event the mlx5_txpp_gather_timestamp()
is reported as "not used" causing the compilation warning/error.
This patch moves the routine to the conditional block.

Fixes: 244788055199 ("net/mlx5: introduce clock queue service routine")
