[PATCH 4/4] Move USE_WCACHING to drivers/block/pktcdvd.c

From: Palmer Dabbelt <palmer@dabbelt.com>

I don't think this was ever intended to be exposed to userspace, but
it did require an "#ifdef CONFIG_*". Since the name is kind of
generic and was only used in one place, I've moved the definition to
the one user.
