[libvirt] [PATCH] Fix possible NULL pointer dereference
If there are no references remaining to the object, vm is set to NULL
and vm->persistent cannot be accessed. Fixed by this trivial patch.
* src/qemu/qemu_driver.c (qemudDomainCoreDump): Avoid possible
NULL pointer dereference on --crash dump.

Okay, I have pushed the 2 patches, I got a merge error in the
cleanup section of the QEmu dump entry point, which I manually
applied hope it's fine, I also had to cleanup some TAB used for
indentation (hint use "make syntax-check" to catch those),
Here is a little adjustment. Thanks!
