cpulimit: Explicitly ignore pa_read() return value.

It doesn't matter if the function fails (I'm not sure if
it's even possible), because the read data isn't used for
anything and the daemon will terminate in any case. The
void cast should get rid of a Coverity warning.

Removing the whole pa_read() call should be ok too, but I
guess it's nice to clean up the pipe before terminating...
