csum_tcpudp_magic() is only a few instructions, and does not modifies any other

This patch makes it inline by use of the already existing csum_tcpudp_nofold()
function.

The 64-bit version is pretty similar to the 32-bit -- why only use
csum_tcpudp_nofold() on 32-bit?
I did it only on 32-bit because I have no way to test it on 64-bits, but
I can do it for 64 bits as well, no problem.
