bnxt_en: Restore PTP tx_avail count in case of skb_pad() error
The current code only restores PTP tx_avail count when we get DMA
mapping errors. Fix it so that the PTP tx_avail count will be
restored for both DMA mapping errors and skb_pad() errors.
Otherwise PTP TX timestamp will not be available after a PTP
packet hits the skb_pad() error.
Fixes: 83bb623c968e ("bnxt_en: Transmit and retrieve packet timestamps")
