igb: add statistic indicating number of skipped Tx timestamps
The igb driver can only handle one Tx timestamp request at a time.
This means it is possible for an application timestamp request to be
ignored.
There is no easy way for an administrator to determine if this occurred.
Add a new statistic which tracks this, tx_hwtstamp_skipped.
