Log Message:
ssh mostly ignores the return value of select(), so if the timeout
expired it would assume that all input set descriptors had activity.

In case we get rv == 0 from the poll backend, zero out the fd sets
to signal that in fact no descriptors have activity.

Before this commit ssh was "jittery" when run through a rump tcp/ip
stack (interactive sessions kept blocking on stdin and you had to
"peddle" the connection).  Now it works smoothly ... or at least
smoothly enough so that this commit could be done through a rump
tcp/ip stack:
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
root     ssh        125    0 tcp    localhost.65517       cvs.netbsd.org.22
