dmaengine/ste_dma40: fix Oops due to double free of client descriptor
The client list may exist in two lists at the same time. This makes free
fail since the same desc is freed multiple times. Remove desc from
client list when adding it to the pending queue. Move free of client owned
descriptors from free_dma() to terminate_all().
