[PATCH] usb: cdns3: Removes duplicated call to the cdns3_exit_roles function

From: Pawel Laszczak
Date: Thu Aug 13 2020 - 03:12:04 EST


To avoid double calling of function cdns3_exit_roles when initialization
failed patch removes invoking this function from cdns3_core_init_role.
This function is invoked again from cdns3_probe when
cdns3_core_init_role returns error code.
