In a busy network, especially with flow control enabled, we may
experience timestamp query failures fairly regularly. After a while,
dmesg may be flooded with timestamp query failure error messages.

Silence the error message from the low level hwrm function that
sends the firmware message.  Change netdev_err() to netdev_WARN_ONCE()
if this FW call ever fails.
