[libvirt] [PATCH] Fix memory leak in virObjectEventCallbackListRemoveID()

[Nehal J Wani]

While running objecteventtest, it was found that valgrind pointed out the
following memory leak:

==13464== 5 bytes in 1 blocks are definitely lost in loss record 7 of 134
==13464==    at 0x4A0887C: malloc (vg_replace_malloc.c:270)

 Should we be introducing virObjectMetaFree() and/or virObjectEventCallbackFree() ?
