fscache: Remove the contents of the fscache driver, pending rewrite
Remove the code that comprises the fscache driver as it's going to be
substantially rewritten, with the majority of the code being erased in the
rewrite.
A small piece of linux/fscache.h is left as that is #included by a bunch of
network filesystems.
