dm log: fix create_log_context to use logical_block_size of log device
create_log_context() must use the logical_block_size from the log disk, where the I/O happens, not the target's logical_block_size. Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
