Jeremy Fitzhardinge b318606e41 xen/hvc: make sure console output is always emitted, with explicit polling ...

commit 7825cf10e31c64ece3cac66fb01a742f1094da51 upstream.

We never want to rely on the hvc workqueue to emit output, because the
most interesting output is when the kernel is broken.  This will
improve oops/crash/console message for better debugging.

Instead, we force-poll until all output is emitted.
