2b94a3ab31 cleaner: Move sort functionality to flush_data abstraction 
The flush_data is used by ocf_cleaner_do_flush_data_async(), which means
that callers of ocf_cleaner_fire() are now expected to guarantee that
entries are returned by getter in a sorted order. Currently the only case
when ocf_cleaner_fire() is called directly is for request cleaning, and
the request map is sorted by definition.

Majority of management operations should be blocked for detached cache,
although adding and removing cores should be possible.

de07458ff2 Common context for cache stop and cache detach 
Stop and cache detach were already sharing contexts implicitly, which allowed
to reuse some functions in both pipelines. However, changing the context structs
could lead to not obvious bugs.

To prevent such errors both methods now share context structure explicitly

2a97de8792 Detach finish: destroy stop pipeline before cmpl 
'stop_pipeline' filed may be reused during cache lifetime (e.g. when cache is
detached and attached again - the pipeline would be freed and then
re-allocated). Calling completion after detach before freeing the pipeline may
lead to race condition.

2398412622 cleaner: Unlock cache mngt lock from queue context 
Cache mngt lock cannot be unlocked from io completion context (which is
potentially atomic context) as it may involve sleeping operations.
Modify cleaner utility to support rescheduling to queue context before
calling the completion. Update cleaning policies to use that option.

fd489e3a30 Fix potential deadlock in discard 
HB lock takes inclusive metadata lock, which is taken also by metadata
flush, thus trying to call metadata flush under HB lock attempts to take
this lock recursively. In that case, if in the meantime some other thread
would try to take exclusive metadata lock, the inner inclusive lock would
block (because the lock keeps the order), with outer inclusive lock still
held, leading to a deadlock.

d57c9bb51d Unlock request in PT using ocf_req_unlock() 
There are situations when we can end up in engine_pt with cache lines
locked for write. One example is engine_rd falling back to engine_pt after
failure during cache line preparation, where write lock has been already
taken. To handle this situation properly, unlock request using more general
unlock function.
