[issue2067] sound/pcm: "play interrupt timeout, channel dead"

["Matthias Rampke \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

New submission from Matthias Rampke <matthias.rampke@googlemail.com>:

this fixes a "pcm0:virtual:0:dsp0.2: play interrupt timeout, channel dead" error 
and sound breaking off after a few seconds of playback I encountered on my 
Thinkpad X40. It was discussed on freebsd-current in 2004[1] but that code is no 
longer present in FreeBSD while we still have it.

The patch[2] removes a line fixing a channel timeout to 1 tick instead of the 
value calculated immediately beforehand, thus restoring the calculation.
