staging: line6: eliminate useless index_out variable
Playback urbs use the index_out counter to decide which part of the
playback buffer to use. Since the urb already has a unique index in
range [0, LINE6_ISO_BUFFERS) there is no need to keep a separate
counter.
Use the urb index instead. This also eliminates the possibility of two
urbs using the same playback buffer space if they ever complete
out-of-order for some reason.
