don't repeat select()

The interfaces main loop repeats the select() (non-blocking) after an event was handled. I do not see any reason for that, since all events should be handled after the first select(). This double select() does nothing than consume more CPU cycles. git-svn-id: https://svn.musicpd.org/mpd/trunk@7213 09075e82-0dd4-0310-85a5-a0d7c8717e4f
