dm snapshot: create function for chunk_is_tracked wait
Move the __chunk_is_tracked() loop into a separate function as we will
also need to call it from the write path in the rare case of conflicting
writes to the same chunk.
Originally introduced in commit a8d41b59f3f5a7ac19452ef442a7fc1b5fa17366
("dm snapshot: fix race during exception creation").
