powerpc/pseries/dlpar: Fix a missing check in dlpar_parse_cc_property()

[ Upstream commit efa9ace68e487ddd29c2b4d6dd23242158f1f607 ]

In dlpar_parse_cc_property(), 'prop->name' is allocated by kstrdup().
kstrdup() may return NULL, so it should be checked and handle error.
And prop should be freed if 'prop->name' is NULL.
