Subject: [net 12/14] net/mlx5e: Fix wrong delay calculation for overflow check scheduling

From: Eugenia Emantayev <eugenia@...lanox.com>

The overflow_period is calculated in seconds. In order to use it
for delayed work scheduling translation to jiffies is needed.

Fixes: ef9814deafd0 ('net/mlx5e: Add HW timestamping (TS) support')
