docs: networking: replace skb_hwtstamp_tx with skb_tstamp_tx 



Tiny doc fix. The hardware transmit function was called skb_tstamp_tx
from its introduction in commit ac45f602 ("net: infrastructure for
hardware time stamping") in the same series as this documentation.

Fixes: cb9eff09 ("net: new user space API for time stamping of incoming and outgoing packets")

  and hardware timestamping is not possible (SKBTX_IN_PROGRESS not set).

- As soon as the driver has sent the packet and/or obtained a

  hardware time stamp for it, it passes the time stamp back by

  calling skb_hwtstamp_tx() with the original skb, the raw

  hardware time stamp. skb_hwtstamp_tx() clones the original skb and

  calling skb_tstamp_tx() with the original skb, the raw

  hardware time stamp. skb_tstamp_tx() clones the original skb and

  adds the timestamps, therefore the original skb has to be freed now.

  If obtaining the hardware time stamp somehow fails, then the driver

  should not fall back to software time stamping. The rationale is that
