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

Browse Source 
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.
