kvmalloc by limiting the number of targets and parameter size area.
 
 - Fix DM stats to avoid INT_MAX overflow warnings from kvmalloc by
   limiting the number of entries supported.
 
 - Fix DM writecache to support mapping devices larger than 1 TiB by
   switching from using kvmalloc_array to vmalloc_array -- which avoids
   INT_MAX overflow in kvmalloc_node and associated warnings.
 
 - Remove the (ab)use of tasklets from both the DM crypt and verity
   targets. They will be converted to use BH workqueue in future.
