dm log: split suspend
There are now two phases to a suspend in device-mapper -
presuspend and postsuspend. This patch removes the
single 'suspend' in the logging API and replaces it with
'presuspend' and 'postsuspend' functions to align it
better with core device-mapper.
A subsequent patch will make use of 'presuspend'.
