f0564dcf75 Avoid unnecessary metadata flushes in WT 
Flushing metadata in WT is required only if at least of the request's cacheline
changed its state to clean.

c9294d1f06 Reorder metadata updating pattern in WT mode 
There's a possibility that WT write is performed to dirty cache line (i.e. after
switching WB->WT without flush) and status bits change from dirty to clean. If
power failure occurs it might happen that recovery would ignore recent data from
cache and would assume that data is clean while backend storage data is out of
date.

0192ce23dd Reorder metadata updating patter in WB mode 
In WB mode metadata should be updated only if the actuall data had been saved
on disk. Otherwise metadata might be flushed too early and consequently data
corruption might occur.

87f834c793 Move common user and freelist partition data to a new struct 
New structure ocf_part is added to contain all the data common for both
user partitions and freelist partition: part_runtime and part_id.
ocf_user_part now contains ocf_part structure as well as pointer to
cleaning partition runtime metadata (moved out from part_runtime) and
user partition config (no change here).
