Subject[PATCH] removes array_size duplicates
This patch removes some ARRAY_SIZE macro duplicates. There is also one in
arch/um/include/user.h, which isn't fixed here because comments in that file
explicitly state a preference for the 'less fancy' version. If that's the
case as well for any of the other replacements please comment.
