[libvirt] [PATCH 5/8] xen: Resolve Coverity FORWARD_NULL

[John Ferlan]

Coverity found that xenXMConfigCacheAddFile has an error path in which
no error message and a -1 was not returned which could have resulted in
a NULL dereference in a VIR_DEBUG statement and of course an erroneous
0 value returned!
