[PATCH 06/12] making the kernel -Wshadow clean - fix checksum

[Jesper Juhl <jesper.juhl@gmail.com>]

Some -Wshadow fixes for include/[asm-i386|net]/checksum.h

 include/asm/checksum.h:185: warning: declaration of 'sum' shadows a parameter
 include/asm/checksum.h:181: warning: shadowed declaration is here
 include/net/checksum.h:33: warning: declaration of 'sum' shadows a parameter
 include/net/checksum.h:31: warning: shadowed declaration is here

these show up several times each.
