Leak introduced in commit 16ebf10f (v1.2.6), detected by valgrind:
==9816== 216 (96 direct, 120 indirect) bytes in 6 blocks are definitely lost in loss record 665 of 821
==9816== at 0x4A081D4: calloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so)
==9816== by 0x50836FB: virAlloc (viralloc.c:144)
==9816== by 0x1DBDBE27: udevProcessPCI (node_device_udev.c:546)
==9816== by 0x1DBDD79D: udevGetDeviceDetails (node_device_udev.c:1293)
While at it, fix switch statements to be a bit more vocal if we forget
some cases when adding new devices.
* src/conf/node_device_conf.c (virNodeDeviceDefFormat)
(virNodeDevCapsDefParseXML): Drop default case.
(virNodeDevCapsDefFree): Likewise, and clear pci_express under pci
case.

I could be persuaded to split this into two patches.
