9dc1381b77 Refactor ocf_submit_cache_reqs map indexing
Refactoring ocf_submit_cache_reqs to make it clear that
req->map is accessed at index derived from offset argument,
not necesarily starting at 0.

82e8c55f4a Write-only cache mode
Write-only cache mode is similar to writeback, however read
operations do not promote data to cache. Reads are mostly serviced
by the core device, only dirty sectors are fetched from the cache.

1373471af7 Introduce OCF_CMPL_RET() macro
This simplifies cases when we want to call completion callback
and immediately return from void-returning function, by allowing
to explicitly express programmers intent. That way we can avoid
cases when return statement is missing by mistake (this patch
fixes at least one bug related to this).

91e0345b78 Implement asynchronous attach, load, detach and stop
NOTE: This is still not the real asynchronism. Metadata interfaces
are still not fully asynchronous.

e69894e398 Set io_queue for some requests
Propagate id of ocf_queue where it is possible

This resolves the issue of
  bottom adapter always getting an ocf_io with io_queue = 0,
  no matter from which queue function to bottom adapter was called
