facetimehd: change fthd_channel_ringbuf_send() error handling
...
In the current implementation it returns -1 on error, an offset value
otherwise. Change it to return a negative error value, and add a pointer
to an u32 for receiving the entry offset as an extra argument.
This makes the ugly (u32)-1 return code comparision obsolete, and we
can return a more detailed error code like EAGAIN if all ringbuffer slots
are busy.
