5a71f7c068 validate uuid->size in ocf_volume_init 
Optional uuid parameter to ocf_volume_init() points to UUID object
initialized by the user. We should verify it is not excesively large
as we attempt to allocate a buffer to store a copy of the UUID.

364e36ec7e Revert "fix deinitialization of moved composite volume" 
The proper way to avoid calling on_deinit() callback on an already
deinitialized volume is to deinitialize type callbacks, as it is done
in the previous commit.

This reverts commit a7f70687a9.

b6587ad622 zero volume->type in ocf_volume_deinit() 
After deinitialization of volume there is no need to call back to
type ops. Currently we would erroneously call on_deinit() callback
multiple times if ocf_volume_deinit() is performed more than once,
which we expect to happen and treat as a correct use of API.

f0f6ff219b Set core volume type in metadata on core insert 
ocf_metadata_flush_superblock() is being called on the cache stop, after
deinitialization of the cores (and their volumes), thus accessing core
volume in superblock flushing procedure leads to use-after-free bug.

Fix this by moving volume type setting to the core insertion code.

a7f70687a9 fix deinitialization of moved composite volume 
After moving from a volume, it's priv is assigned to the new owner.
Destroying the volume after moving from it must not attempt to use the
priv, especially not to attempt to deinit member volumes in case of
composite volume.
