libxc: check failure of xc_dom_*_to_ptr, xc_map_foreign_range
The return values from xc_dom_*_to_ptr and xc_map_foreign_range are
sometimes dereferenced, or subjected to pointer arithmetic, without
checking whether the relevant function failed and returned NULL.
Add an appropriate error check at every call site.
Changes in the 4.2 backport of this series:
* Fix tools/libxc/xc_dom_x86.c:setup_pgtables_x86_32.
* Fix tools/libxc/xc_dom_ia64.c:start_info_ia64.
* Fix tools/libxc/ia64/xc_ia64_dom_fwloader.c:xc_dom_load_fw_kernel.
This is part of the fix to a security issue, XSA-55.
