cluster/dht: dump the layout information of directories only

Browse Source 
testcase:
The changes are for removing gf_log from statedump related sections in dht and
using pthread_mutex_trylock in statedump sections. Changes are internal. So
tests were done by attaching gdb to the process and executing by manually
changing the values of some of the pointers.
