property2xml, nil values

Hi again,

in src/plugins/cim/sfcc-interface.c, function property2xml(), around line 296:

} else if (data.type == CMPI_null && data.state == CMPI_nullValue) {

should be

} else if (data.type == CMPI_null || data.state == CMPI_nullValue) {

so that wsman returns empty arrays that are not of type CMPI_null.
