net: enetc: keep track of correct Tx BD count in enetc_map_tx_tso_buffs()

Browse source

commit da291996b1 upstream.

When creating a TSO header, if the skb is VLAN tagged, the extended BD
will be used and the 'count' should be increased by 2 instead of 1.
Otherwise, when an error occurs, less tx_swbd will be freed than the
actual number.
