Changed paths: M lib/system/nuttx/mutex.h

Log Message: ----------- mutex: change the libmetal nuttx mutex to recursive mutex

To avoid the crash when lock are acquired twice, one case is in the destory process: we hold the rpdev->lock to iterate the rpdev->endpoints to destory all the endpoints, but rpmsg_destroy_ept() may send the name service message, and need acquire the rpdev->lock again to lead crash.
