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.
Fixes: 118612d519d8 ("bnxt_en: Add PTP clock APIs, ioctls, and ethtool methods")
