qede: Handle infinite driver spinning for Tx timestamp.
In PTP Tx implementation, driver kept scheduling a poll thread until the
timestamp is available. In the error scenarios (e.g. app requesting the
timestamp for non-ptp packet), this thread kept waiting for the timestamp
forever. This patch add changes to report such scenario as an error and
terminate the thread. Added a timeout of 2 seconds i.e., max time to wait
for Tx timestamp. Added a stat value ptp_skip_txts for reporting the number
of packets for which Tx timestamping is skipped.
