When offloading TCP checksum generation to hardware, one sets the macro
CHECKSUM_GEN_TCP to zero. As a side effect, a local variable becomes
orphaned in two functions in the TCP code. This in turn cause compiler
warnings about unused variables.

This patch fixes the issue by placing the appropriate ifdefs, and it
applies to the 1.4.1 branch.

The 1.4.1 branch is *not* continued right now, development is continued for 1.5.0. The bug you mentioned is already fixed in the current code.
