dm snapshot: introduce account_start_copy() and account_end_copy()
[ Upstream commit a2f83e8b0c82c9500421a26c49eb198b25fcdea3 ]
This simple refactoring moves code for modifying the semaphore cow_count
into separate functions to prepare for changes that will extend these
methods to provide for a more sophisticated mechanism for COW
throttling.
