cli: removed extra dict unrefs and memory leaks
PROBLEMS ADDRESSED: a. The following change http://review.gluster.com/#change,3948 introduces extra dict unrefs in cli. b. There are instances of memory leak in gf_cli_*_cbk functions. FIX: Problem (a) is fixed by ensuring the dict is ref'd (indirectly at the time of creation) and unref'd (in CLI_STACK_DESTROY) ONLY once. The following is the rationale behind this approach: The number of refs and unrefs on dict varies across the different commands that use it. The cli thread MUST wait for the gf_cli_*_cbks to complete before the frame is destroyed. This rules out the need to do extra refs and unrefs in the code path. Problem (b) is fixed by doing unref on dicts that are created for the purpose of unserializing the response but never freed in gf_cli_*_cbk functions.
