usb: chipidea: msm: ci_hdrc_msm_probe() missing of_node_get()

Browse source 
Boot fails for qcom-apq8074-dragonboard on 4.13-rc1 with error:
OF: ERROR: Bad of_node_put() on /soc/usb@f9a55000

The error will occur if the configuration is set to:
   CONFIG_OF_OVERLAY y
   CONFIG_OF_UNITTEST y
   CONFIG_OF_DYNAMIC y
   CONFIG_OF_RESOLVE y

If CONFIG_OF_DYNAMIC is enabled then of_node_release() detects an
attempt to release a node that is still attached to the device tree.
