186bfbc704 Fix cache reference management in get/set seq cutoff threshold 
ocf_core_get_cache does not increment cache reference count, so
it shouldn't be paired with cache_put

8b0d10952f Don't generate core name when adding core to corepool. 
When core frome corepool is added to cache, it's old name is loaded and cores
in corepool cannot be referenced by name anyway so new name is not needed.

a7390aa6fc Return error on invalid core id 
Instead of silently allowing for any core_id in order to set
core parameter for all cores in cache, check explicitly for
special value (OCF_CORE_ID_INVALID) which means that no core
has been selected.

76acefd831 After loading cache mark used core ids. 
Since OCF doesn't use core and cache ids anymore adapter has to track occupied
ids on its own. After loading cache, ids of all loaded cores should be marked as
occupied, otherwise adding new core without explicit specifying core id will
fail.

eab04f02fb modules: Fixed getting running kernel ver 
Kernel's 'make kernelversion' does not print some extra version tags
(like 4.19-xxx) so there was a problem with installing CAS on some
kernels. Moved it back to using just 'uname -r'.

95af3c6f9f Move to blk-mq block interface. 
Currently Open-CAS uses single queue block interface,
which is removed in kernel in version 5.0.
From this moment on Open-CAS supports only blk-mq,
and single queue is not supported any longer.
