usb: dwc3: qcom: Fix NULL vs IS_ERR checking in dwc3_qcom_probe

Browse source 
[ Upstream commit b52fe2dbb3 ]

Since the acpi_create_platform_device() function may return error
pointers, dwc3_qcom_create_urs_usb_platdev() function may return error
pointers too. Using IS_ERR_OR_NULL() to check the return value to fix this.
