staging: line6: fix playback urb transfer buffer calculation
The playback urb transfer buffer calculation does not factor in
LINE6_ISO_PACKETS. Buffer memory is organized like this in the driver:
Buffer 0 Buffer 1 ...
[Packet 0, Packet 1, ...][Packet 0, Packet 1, ...][Packet 0, ...]
However, we're lucky that LINE6_ISO_PACKETS is currently defined as 1 so
this patch does not change any behavior. It's still worth including
this fix in case the LINE6_ISO_PACKETS value is changed in the future.
