[NET]: Treat the sign of the result of skb_headroom() consistently
In some places, the result of skb_headroom() is compared to an unsigned integer, and in others, the result is compared to a signed integer. Make the comparisons consistent and correct. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
