net: Kill skb_truesize_check(), it only catches false-positives.

[ Upstream commit 92a0acce186cde8ead56c6915d9479773673ea1a ]

A long time ago we had bugs, primarily in TCP, where we would modify
skb->truesize (for TSO queue collapsing) in ways which would corrupt
the socket memory accounting.

skb_truesize_check() was added in order to try and catch this error
more systematically.

However this debugging check has morphed into a Frankenstein of sorts
and these days it does nothing other than catch false-positives.
