tg3: Use slab_build_skb() when needed

Browse source

The tg3 driver will use kmalloc() under some conditions. Check the
frag_size and use slab_build_skb() when frag_size is 0. Silences
the warning introduced by commit ce098da149 ("skbuff: Introduce
slab_build_skb()"):

	Use slab_build_skb() instead
	...
	tg3_poll_work+0x638/0xf90 [tg3]
