dcd/stm32_fsdev: restore CH32 EP0 CONTROL type when stalling
The CH32 workaround only restored EP0 to CONTROL in edpt_xfer(). When
the stack rejects a control write with data (handle_ctr_setup having
already switched EP0 to BULK) it stalls EP0 via dcd_edpt_stall() without
ever calling dcd_edpt_xfer(), leaving EP0 typed BULK+STALL. As SETUP
recognition is tied to CONTROL-typed endpoints, the host's recovery
SETUP (which should auto-clear the stall) would be ignored, wedging EP0
until a bus reset.
Restore CONTROL for EP0 in the same exclusive write that sets the STALL
status. DFU download-in-wrong-state is a concrete trigger.
