54f75ba492 Introduce ocf_req_forward_volume_*() 
Those are meant to be used in context where no cache nor queue is
available (typically at very early stage of initialization). We reuse
cache_forward* callback and counter, because they will not be used
in this context anyway.

0cd2393aaf Implement forward ops in composite volume 
Allow composite volume to forward the io to sub-volumes, splitting it
into several forward operations when needed. This is still done with
zero allocations, making forward even more efficient when combined with
composite volume.
