Volume close should not close underlying device until all
I/O targeting this volume are deallocated. To achieve this
a reference counter is added to volume. Counter value
matches number of I/O objects associated with volume. Counter
is freezed when volume is closed, blocking allocation of new
I/O objects.

There is a risk that without uuid.data pointer denitialization it will
be freed during original volume deinit, zeroing uuid.data pointer
prevents that.

This pointer is used to provide optional volume specific data
from the user down to bottom volume open callback. volume_params
is provided to OCF in ocf_mngt_cache_device_config.volume_params.
