Don't copy SB1 cache error handler to uncached memory.

This may have made sense on a paranoid day with pass 1 BCM1250 processors

The type of sum in csum_tcpudp_nofold is "unsigned int", so when we assign
...
to it in an asm() block, and we're running on a system with 64-bit
registers, it is vitally important that we sign extend it correctly before
returning to C. Otherwise the stray high bits will be preserved into
csum_fold, and on the SB-1 processor, 32-bit arithmetic on a non
sign-extended register will yield surprising results.
This caused incorrect checksums in some UDP packets for NFS root. The
problem was mild when using a 10.0.1.x IP address, but severe when
using 192.168.1.x.
