    bnxt_en: Reset PTP tx_avail after possible firmware reset
    
    [ Upstream commit faa12ca245585379d612736a4b5e98e88481ea59 ]
    
    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.
