dm persistent data: cleanup dm-thin specific references in text
DM's persistent-data library is now used my multiple targets so exclusive references to "pool" or "thin provisioning" need to be cleaned up. Adjust Kconfig's DM_DEBUG_BLOCK_STACK_TRACING text and remove "pool" from a block manager error message. Signed-off-by: Mike Snitzer <snitzer@redhat.com> Acked-by: Joe Thornber <ejt@redhat.com>
