[Xen-changelog] [xen-unstable] Shadow code printing adjustments.

[Xen patchbot-unstable <patchbot-unstable@xxxxxxxxxxxxxxxxxxx>]

# HG changeset patch
# User Keir Fraser <keir@xxxxxxxxxxxxx>
# Date 1192094445 -3600
# Node ID 8d51b80fcb6f002f53a5ab293f1ab87384837397
# Parent  ab5b615867ee7913ae6f0afe49f7a5e8ad20ea94
Shadow code printing adjustments.

Messages prior to BUG() should always be displayed, not just when
DEBUG_TRACE_DUMP is defined (which by default it isn't). Convert them
from SHADOW_PRINTK() to SHADOW_ERROR().
