src/portable/wch/hcd_ch32_usbfs.cto improve:After the commit 13e0b0c, some USB device couldn't be enumerated at CH32 USBFS Host.
Validated on real hardware with
examples/host/cdc_msc_hid, USB Thumbstick, USB-CDC dongle, USB Keyboard and the CH32V203 MCU board "Suzuno32RV" (which I developed and sold by Japanese manufacture BitTradeOne).
