net: stmmac: generate software timestamp just before the doorbell

Browse source

Make sure the call of skb_tx_timestamp is as close as possbile to the
doorbell.

The patch also adjusts the order of setting SKBTX_IN_PROGRESS and
generate software timestamp so that without SOF_TIMESTAMPING_OPT_TX_SWHW
being set the software and hardware timestamps will not appear in the
error queue of socket nearly at the same time (Please see __skb_tstamp_tx()).
