Hello everyone!
When implementing some custom qemu capability I cought this bug when
some string with '*' pattern is not contained in schema, and
virQEMUQAPISchemaTraverseObject
passes NULL ptr to virJSONValueObjectHasKey.

New subject: [PATCH 1/1] qemu: qapi: fix potential SIGSEGV in virQEMUQAPISchemaTraverseObject()
We need to check obj ptr before passing it to
virJSONValueObjectHasKey(). If it's NULL it will fail with SIGSEGV.
