[PATCH] MIPS: fix module.c build for 32 bit

[Jonas Gorski]

Fixes the following build failure introduced by "Make most arch
asm/module.h files use asm-generic/module.h".

  CC      arch/mips/kernel/module.o
arch/mips/kernel/module.c:250:14: error: 'reloc_handlers_rela' defined but not used [-Werror=unused-variable]
cc1: all warnings being treated as errors

make[6]: *** [arch/mips/kernel/module.o] Error 1

I don't mind this patch being squashed into the original patch. The
patch isn't in any stable git yet, so I assume any git id would be
outdated soon anyway.

Linus, I CC'd you because there already is a pending pull request for
this patch.

David, it would have been nice if the mentioned patch had made it to 
linux-mips. I just caught this more or less by accident by building
linux-next.
