[PATCH 3/3] shell: avoid unnecessary busy cursor sending when not-responsing-ping client

[juan.j.zhao at linux.intel.com]

From: Juan Zhao <juan.j.zhao at linux.intel.com>

When the client didn't response to ping event in time, the server
 will do "set_busy_cursor" again and again. In fact it should only need to
 set it at the first time. Because handle_pointer_focus could help to set it,
 when the application was focused.
