[PATCH 5/7] IB/qib: clear 6120 hardware error register

[Ralph Campbell <ralph.campbell-h88ZbnxC6KDQT0dZR+AlfA@public.gmane.org>]

The hardware error register needs to be cleared or another interrupt
will be generated, thus causing an infinite loop.
This is a regression introduced when removing debug output.
