[PATCH] fix mm/rmap.c build failure if CONFIG_SWAP is not defined (2.6.10-rc3-bk16)

[Jesper Juhl <juhl-lkml@dif.dk>]

I just tried a allnoconfig build of 2.6.10-rc3-bk16, and it fails on 
mm/rmap.c since swap_token_default_timeout is not defined by 
include/linux/swap.h if CONFIG_SWAP is not defined.  The patch below just 
makes the small bit that uses swap_token_default_timeout be conditionally 
build depending on CONFIG_SWAP being defined or not, but I have no idea if 
this is the proper way to fix this (it does allow it to build though).
