Joe Thornber 086fbbbda9 dm thin metadata: make dm_thin_find_mapped_range() atomic 
Refactor dm_thin_find_mapped_range() so that it takes the read lock on
the metadata's lock; rather than relying on finer grained locking that
is pushed down inside dm_thin_find_next_mapped_block() and
dm_thin_find_block().
