glusterd: memory leak in get-state

Problem: gluster get-state command is leaking the memory when
geo-replication session is configured.

Cause: In glusterd_print_gsync_status(), we are trying to get
reference to the keys of gsync_dict. The references to keys of
gsync_dict are stored status_vols[i]. status_vols[i] are
allocated with a memory of size of gf_gsync_status_t.

Solution: Need not to use a array of pointers(status_vals), using
a pointer to hold the reference to a key of gsync_dict is sufficient.

Followed the below steps for testing:
1. Configured geo-rep session
2. Ran gluster get-state command for 1000 times.

Without this patch, glusterd's memory was increasing significantly
(around 22000KB per 1000 times), with this patch it reduced (1500KB
per 1000 times)
