Variables that are set while adding the corresponding BO in transfer list
should be cleaned when flushing them out of transfer list prematurely.

After this patch we do not need some of the cleanup done in release_dbc()

This patch would also pave the way to have a central location to clean BO,
during an undesired situation.
