All fabrics drivers grab an extra reference during ->create_ctrl, which we will drop when releasing the file descriptor that we used to create the device. By the time we call ->delete_ctrl in nvmf_create_ctrl we must still have that reference because we are still in a ->write call and thus ->release can't have been called yet.
