tcp_splice: Use unsigned to represent side
Currently, we use 'int' values to represent the "side" of a connection,
which must always be 0 or 1. This turns out to be dangerous.
In some cases we're going to want to put the side into a 1-bit bitfield.
However, if that bitfield has type 'int', when we copy it out to a regular
'int' variable, it will be sign-extended and so have values 0 and -1,
instead of 0 and 1.
To avoid this, always use unsigned variables for the side.
