Subject: [PATCH] NET: Remove unneeded type cast in skb_truesize_check()

The (int) type cast in skb_truesize_check() is unneeded: without it, all
the variable types in the conditional expression are unsigned integers.  As
it stands, the type cast causes a comparison between a signed and an
unsigned integer, which can produce unexpected results.
