Subject: [PATCH v6 05/14] ceph-fs: replace direct access of d_count with the d_count() helper

All readonly references to d_count outside of the core dcache code
should be changed to use the new d_count() helper as they shouldn't
access its value directly.  There is no change in logic and everything
should just work.
