svm: fix producer deadlock in svm_msg_q_wait()
1. When producer invokes svm_msg_q_wait() in svm_msg_q_lock_and_alloc_msg_w_ring(), queue mutex is held by itself.
2. Sometimes, svm msg queue is not full and ring is full, svm_msg_q_wait() do nothing with mutex held, consumer will blocking at svm_msg_q_send_signal().
Type: fix
