gluster/CLI: crash upon executing "peer status" command
Problem: While doing "gluster peer status", cli_cmd_peer_status_cbk() creates the frame and passes as arg to gf_cli_list_friends() which sets frame->local to GF_CLI_LIST_PEERS flag (value: 0x1). It expects gf_cli_list_friends_cbk() [invoked through cli_cmd_submit()] to reset frame->local to NULL. But if cli_cmd_submit() fails some where before gf_cli_list_friends_cbk() gets invoked, then the flag value remains in frame->local and causes a SEGV while destroying the stack i.e. [CLI_STACK_DESTROY => cli_local_wipe()]. Fix: In gf_cli_list_friends(), if cli_cmd_submit() fails, then reset the value of frame->local to NULL.
