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

Browse source 
[ Upstream commit efa9ace68e ]

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.
