fix preprocessor idiocy in reiserfs
#x blocks expansion of macro argument, but it won't do you any
good if it's already been expanded... As it is, RFALSE(cond, ....)
ended up with stringified _expanded_ cond. Real fun when cond contains
something like le32_to_cpu() and you are on a big-endian box...
