patch #1 add a flag to zpool, then zswap used to determine if zpool

patch #2 set flag sleep_mapped to true indicates that zbud/z3fold can
sleep in atomic context. zsmalloc didin't support sleep in atomic context,
so not set that flag to true.

Haven't been able to actually test these yet, but looks good to me so far, so
I have tested that this patch works well，it's better to double check by
you or someone else.

Please wait a bit for Mike, Sebastian or me to actually test this.
Also, keep them CC'd explicitly if you are to come up with a new
version for some reason.
Best regards,
