"Use slab_build_skb() instead" deprecation warning triggered by tg3

[Fiona Ebner]

Hi,
we've got a user report about the WARN_ONCE introduced by ce098da1497c
("skbuff: Introduce slab_build_skb()") [0]. The stack trace indicates
that the call comes from the tg3 module. While this is still kernel 6.2
and I can't verify that the issue is still there with newer kernels, I
don't see related changes in drivers/net/ethernet/broadcom/tg3.* after
ce098da1497c, so I thought I should let you know.
