Since the ops->evict comes from zswap (and is never omitted), if we do

This allows frontswap to successfully manage multiple implementations
by keeping a list of them all.

Add dynamic creation of pools. Move the static crypto compression
per-cpu transforms into each pool. Add a pointer to zswap_entry to
the pool it's in.
This is required by a separate patch which enables changing the
zswap zpool and compressor params at runtime.

Seth, as far as the design, from your previous comments I assume you
ram mutex. They are thus replaced with simplified functions
that clearly indicate that all params for a module are being blocked, both
for read and write access.

Change the pr_info() calls to pr_debug(). There's no need for the extra
verbosity in the log. Also change the msg formats to be consistent.

So instead, this copies the idea from __param_check() to add inline
constant functions to check the param permissions. That way no extra
bits are needed.
