net/mlx5: Skip clock update work when device is in error state

When device is in error state, marked by the flag
MLX5_DEVICE_STATE_INTERNAL_ERROR, the HW and PCI may not be accessible
and so clock update work should be skipped. Furthermore, such access
through PCI in error state, after calling mlx5_pci_disable_device() can
result in failing to recover from pci errors.

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