In this patch, the xc_domain_dumpcore_via_callback() in xc_core.c of
libxc is modified. Previously, the xc_domain_dumpcore_via_callback()
did not respond to error when copy_from_domain_page() failed.
In other words, the dump core remained silent even if mapping the domain
memory failed and its page could not be copied. When this happened,
erroneous data had been dumped to the file without the user realizing it.
Now, it has been modified so that if copy_from_domain_page fails,
this fact is recorded in the logfile and make imcoplerte-list.
However even in such cases, the dumping will continue as before.
