dm stats: check for and propagate alloc_percpu failure (2023-03-16 13:37:06 -0400)

Please pull, thanks.

----------------------------------------------------------------
- Fix DM thin to work as a swap device by using 'limit_swap_bios' DM target flag (initially added to allow swap to dm-crypt) to throttle the amount of outstanding swap bios.

- Fix DM crypt soft lockup warnings by calling cond_resched() from the cpu intensive loop in dmcrypt_write().

- Fix DM crypt to not access an uninitialized tasklet. This fix allows for consistent handling of IO completion, by _not_ needlessly punting to a workqueue when tasklets are not needed.

- Fix DM core's alloc_dev() initialization for DM stats to check for and propagate alloc_percpu() failure.
