Stephen Hemminger f73332fc39 ixgbe: simplify padding and length checks 
The check for length <= 0 is bogus because length is unsigned, and network
stack never sends zero length packets (unless it is totally broken).

The check for really small packets can be optimized (using unlikely)
and calling skb_pad directly.
