hw/pci/pcie_aer.c: fix buffer overruns on invalid state load
4) CVE-2013-4529
hw/pci/pcie_aer.c pcie aer log can overrun the buffer if log_num is
too large
There are two issues in this file:
1. log_max from remote can be larger than on local
then buffer will overrun with data coming from state file.
2. log_num can be larger then we get data corruption
again with an overflow but not adversary controlled.
Fix both issues.
