[Libvirt-cim] [PATCH 02/19] Coverity: Resolve CHECKED_RETURN - _generic_infostore_open()

[John Ferlan]

(7) Event check_return:
    Calling function "fstat(isc->fd, &s)" without checking return value.
    This library function may fail and return an error code.
196             fstat(isc->fd, &s);

Resolve by adding if (fstat->isc->fd, &s) < 0)
