[PATCH] net: fix print in skb_panic()

[gaoxingwang <gaoxingwang1@huawei.com>]

skb->len and sz are printed as negative numbers during the panic:
skbuff: skb_under_panic: text:ffffffff8e2d3eac len:-1961180312 put:-1961180408 head:ffff88800b6ac000 data:ffff887f804ffe78 tail:0x1e0 end:0xec0 dev:team0

Use %u to print skb->len and sz,because they are defined as unsigned int.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
