[PULL 3/5] numa: Add missing \n to error message

From: Greg Kurz <address@hidden>

If memory allocation fails when using -mem-path, QEMU is supposed to print
out a message to indicate that fallback to anonymous RAM is deprecated. This
is done with error_printf() which does output buffering. As a consequence,
the message is only printed at the next flush, eg. when quiting QEMU, and
it also lacks a trailing newline:

qemu-system-ppc64: unable to map backing store for guest RAM: Cannot allocate 
qemu-system-ppc64: warning: falling back to regular RAM allocation
QEMU 4.1.50 monitor - type 'help' for more information
(qemu) q
This is deprecated. Make sure that -mem-path  specified path has sufficient 
resources to allocate -m specified RAM amountgreg@boss02:~/Work/qemu/qemu-spapr$

Add the missing \n to fix both issues.
