- don't let CHANF_AUTO hijack other channels.

With CHANF_OVERLAP this isn't needed anymore - any sound started on CHAN_AUTO can actually play on this channel with overlap implicitly allowed.
This has the added advantage that these sounds can be reliably accessed with other function by using CHAN_AUTO.
