Read stale PTP Tx timestamps from PHY on cleanup. After running out of Tx timestamps request handlers, hardware (HW) stops reporting finished requests. Function ice_ptp_tx_tstamp_cleanup() used to only clean up stale handlers in driver and was leaving the hardware registers not read. Not reading stale PTP Tx timestamps prevents next interrupts from arriving and makes timestamping unusable. Fixes: ea9b847c ("ice: enable transmit timestamps for E810 devices") Signed-off-by:
