staging: vc04_services: no need to save the log debufs dentries

The log entry dentries are only set, never referenced, so no need to
keep them around.  Remove the pointer from struct
vchiq_debugfs_log_entry as it is not needed anymore and get rid of the
separate vchiq_debugfs_create_log_entries() function as it is only used
in one place.
