[issue1884] System completely freezes while listening music (devbuf: malloc limit exceeded)

Some debug messages (I got them while playing in Battle of Wesnoth):

usb0: isoc TD alloc failed // (and sound disappears)

Then, I sent SIGKILL to wesnoth and got endless loop of "ohci_device_isoc_abort:
early return" messages. System, surely, did not respond on anything except
hardware reset.

I do not completely sure that it is connected somehow with previous crashes
(In DragonFlyBSD 2.6 there were no endless loops, in 2.8 loops happen more often
than "normal" crashes), but all works perfectly without using USB sound card
anyway. Maybe there is a bug in OHCI driver?
