When the device acts as a host, it fails to exit the idle state once entered. This prevents new USB gadgets from being detected once plugged in. Commit 032ec49f5351 ("usb: musb: drop useless board_mode usage") removed a is_otg_enabled() check in the try_idle() that prevented from entering idle_state. This was removed because at that time it was not possible to select host-only mode with CONFIG_USB_MUSB_HOST so dual role was always set. Add #ifndef CONFIG_USB_MUSB_HOST around try_idle() callback to prevent from entering idle_state when host-only mode has been selected.
