gro: use min_t() in skb_gro_reset_offset()
commit 7cfd5fd5a9813f1430290d20c0fead9b4582a307 upstream.
On 32bit arches, (skb->end - skb->data) is not 'unsigned int',
so we shall use min_t() instead of min() to avoid a compiler error.
Fixes: 1272ce87fa01 ("gro: Enter slow-path if there is no tailroom")
