This reverts commit a979a6aa009f3c99689432e0cdb5402a4463fb88.

The reverted commit may cause VM freeze on arm64 platform.
Because on arm64 platform, stop a consumer will suspend the VM,
the VM will freeze without a start consumer

It also unconditionally calls del_consumer on the producer, which
isn't exactly expected.
