Subject: [PATCH] usb: dwc3: qcom: Fix memory leak in
dwc3_qcom_interconnect_init
of_icc_get() alloc resources for path handle, we should release it when not
need anymore. Like the release in dwc3_qcom_interconnect_exit() function.
Add icc_put() in error handling to fix this.
Fixes: bea46b981515 ("usb: dwc3: qcom: Add interconnect support in dwc3 driver")
