Add cancel callback feedback thread

- Issue:
Sometimes, ecore_thread_cancel() is blocked in vc_mgr_stop_feedback().

- Solution:
In vc_mgr_stop_feedback(), ecore_thread_cancel() is used, but the cancel
callback is not set. Thus, this patch adds cancel callback and makes the
callback reset the thread variable. Through this patch, the thread
variable will be safely reset.
