cluster/dht: Fixed double UNWIND in lookup everywhere code
In dht_lookup_everywhere_done:
Line: 1194 we call DHT_STACK_UNWIND
and in the same if condition we go ahead and call, goto
unwind_hashed_and_cached; which at Line 1371 calls another UNWIND.
As is obvious, higher frames could cleanup their locals and on
receiving the next unwind could cause a coredump of the process.
Fixed the same by calling the required return post the first unwind
