net: systemport: fix bcm_sysport_insert_tsb()
[ Upstream commit e87474a6e697857df21cff0707a2472abceca8b3 ]
Similar to commit bc23333ba11fb7f959b7e87e121122f5a0fbbca8 ("net:
bcmgenet: fix bcmgenet_put_tx_csum()"), we need to return the skb
pointer in case we had to reallocate the SKB headroom.
Fixes: 80105befdb4b8 ("net: systemport: add Broadcom SYSTEMPORT Ethernet MAC driver")
