Subject: [PATCH v5 09/12] file locking: replace direct access of d_count with the d_count() helper

Because of the d_count change made in dcache.h, all readonly references
to d_count have to 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.
