Fixes#962
Issue mentioned above was caused by race between examine on ocf bdev
(which is partially asynhronous) and bdev delete.
This patch adds new ocf bdev state "starting" it means that register
procedure was started, base on this state, we are not allowing to
destruct vbdev during registering path.
Deleting of vbdev will be still possible on started vbdev or when
register procedure are not started yet.
