usb: dwc2: gadget: don't try to disable ep0 in dwc2_hsotg_suspend
Calling dwc2_hsotg_ep_disable on ep0 (in/out) will lead to the following
logs before returning -EINVAL:
dwc2 49000000.usb-otg: dwc2_hsotg_ep_disable: called for ep0
dwc2 49000000.usb-otg: dwc2_hsotg_ep_disable: called for ep0
To avoid these two logs while suspending, start disabling the endpoint
from the index 1, as done in dwc2_hsotg_udc_stop:
/* all endpoints should be shutdown */
for (ep = 1; ep < hsotg->num_of_eps; ep++) {
if (hsotg->eps_in[ep])
dwc2_hsotg_ep_disable_lock(&hsotg->eps_in[ep]->ep);
if (hsotg->eps_out[ep])
dwc2_hsotg_ep_disable_lock(&hsotg->eps_out[ep]->ep);
}
