cluster/dht: Fix dict_t leaks in rebalance process' execution path
Backport of: http://review.gluster.org/8763
Two dict_t objects are leaked for every file migrated in success codepath.
It is the caller's responsibility to unref dict that it gets from calls to
syncop_getxattr(); and rebalance performs two syncop_getxattr()s per file
without freeing them.
Also, syncop_getxattr() on GF_XATTR_LINKINFO_KEY doesn't seem to be using
the response dict. Hence, NULL is now passed as opposed to @dict to
syncop_getxattr().
