When a sequence is used to perform IO on an esnap clone, differenent
channels will be needed for the blobstore device and the esnap device.
No special esnap handling is required when a sequence is used to perform
IO directly on the blobstore device.
This commit splits bs_sequence_start() into bs_sequence_start_bs() and
bs_sequence_start_blob() to handle these two scenarios. A later commit
introduces special handling of ensap clone blobs.
