usb: cdns3: Fix sheduling with locks held.
Patch fix issue in cdns3_ep0_feature_handle_device function.
The function usleep_range can't be used there because this function is
called with locks held and IRQs disabled in
cdns3_device_thread_irq_handler().
To resolve this issue patch replaces usleep_range with mdelay.
