net/mlx5: use do_aux_work for PHC overflow checks
[ Upstream commit e61e6c415ba9ff2b32bb6780ce1b17d1d76238f1 ]
The overflow_work is using system wq to do overflow checks and updates
for PHC device timecounter, which might be overhelmed by other tasks.
But there is dedicated kthread in PTP subsystem designed for such
things. This patch changes the work queue to proper align with PTP
subsystem and to avoid overloading system work queue.
The adjfine() function acts the same way as overflow check worker,
we can postpone ptp aux worker till the next overflow period after
adjfine() was called.
