ocf: accept optional base in bottom adapter

Browse Source 
Interpret volume->open() options as our vbdev_ocf_base struct.
This is used during metadata probe procedure, when there is no
  vbdev configurations created, so we need to pass base structure
  as option.

This patch is a prepartion for persistant metadata support,
  and it does not change current behavior.
