Subject: [PATCH 4/8] multiboot: fprintf(stderr...) -> error_report()

O-Subject: [RHEL-7.6/7.5.z qemu-kvm PATCH 4/6] multiboot: fprintf(stderr...) -> error_report()
Bugzilla: 1549824

From: Jack Schwartz <jack.schwartz@oracle.com>
Change all fprintf(stderr...) calls in hw/i386/multiboot.c to call
error_report() instead, including the mb_debug macro. Remove the "\n"
from strings passed to all modified calls, since error_report() appends
one.
