[libvirt] [PATCH] util: fixing wrong comparison inside virStoragePermsCopy().

[Julio Faracco]

VIR_STRDUP returns -1 if the string copy was not successful. So, the current
comparison/logic is throwing an error when VIR_STRDUP() returns 1. Only when
source is NULL, it is considering as a success which is not right.
