Vasily Khoruzhick 5c2d0de544 ALSA: line6: hwdep: add support for O_NONBLOCK opening mode 
Currently line6 hwdep interface ignores O_NONBLOCK flag when
opening device and it renders it somewhat useless when using poll.

Check for O_NONBLOCK flag when opening device and don't block read()
if it is set.
