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.
