[libvirt] [PATCH 2/2] nss: Need to check error condition on virJSONValueArraySize
If the 'nleases < 0' on return, then the subsequent call to
findLeaseInJSON will not produce the expected results (passed
in as a size_t, but nleases is a ssize_t). So check if the
returned value < 0 and if so, goto cleanup.
Found by Coverity as a NEGATIVE_RETURNS event
