qcacld-3.0: Enable object manager reference count debug feature

Object manager provides reference count infrastructure for all 4
common objects: psoc, pdev, vdev and peer. Reference count APIs
provide protection from use after free scenarios by making sure
reference counted object is not freed prematurely while its still
in use. Reference count usage requires certain set of disciplines
from components for example:
1) A component 'C' is responsible for all its reference count
2) A component 'B' can't release reference count of a common object
   taken by component 'A'
3) A component can't release a reference count which it has not
   taken.

Enable reference count debug infrastructure such that wrong APIs
usage can be detected and fixed properly.
