ubus: add missing lock for ubus hearing_map

Browse source 
In the build_hearing_map_sort_client there was a dawn_mutex_require
without having locked the mutex resulting in warnings:

  daemon.warn dawn: MUTEX require = 4226B8@ubus.c:2003[2012069248l] - appears to be UNLOCKED!
  daemon.warn dawn: MUTEX require = 4226B8@datastorage.c:694[2012069248l] - appears to be UNLOCKED!

I guess it was a typo, because before entering the
client_array_get_client function the mutex client_array_mutex needs to
be locked and not required.
