powerpc/pseries: add of_node_put() in dlpar_detach_node()
[ Upstream commit 5b3f5c408d8cc59b87e47f1ab9803dbd006e4a91 ]
The previous commit, "of: overlay: add missing of_node_get() in
__of_attach_node_sysfs" added a missing of_node_get() to
__of_attach_node_sysfs(). This results in a refcount imbalance
for nodes attached with dlpar_attach_node(). The calling sequence
from dlpar_attach_node() to __of_attach_node_sysfs() is:
dlpar_attach_node()
of_attach_node()
__of_attach_node_sysfs()
For more detailed description of the node refcount, see
commit 68baf692c435 ("powerpc/pseries: Fix of_node_put() underflow
during DLPAR remove").
