powerpc/pseries: Fix possible leaked device node reference

Browse Source 
Failure return from dlpar_configure_connector when dlpar adding cpus
results in leaking references to the cpus parent device node. Move the
call to of_node_put() prior to checking the result of
dlpar_configure_connector.

Fixes: 8d5ff32076 ("powerpc/pseries: Make dlpar_configure_connector parent node aware")
