bnxt_en: Reset PTP tx_avail after possible firmware reset
It is possible that during error recovery and firmware reset, there is a pending TX PTP packet waiting for the timestamp. We need to reset this condition so that after recovery, the tx_avail count for PTP is reset back to the initial value. Otherwise, we may not accept any PTP TX timestamps after recovery.
