description:
pollts:
Since fds[] does not go to both kernels, set revents to 0 when
splitting the vector.  Now any stale revents passed by the caller
do not get counted as results for the kernel which did not "win"
the poll.

This fixes a situation where a firefox transfer would occasionally
stall.  Now firefox works full speed with a rump networking stack.
