usb: gadget: u_serial: Set start_delayed during suspend

Browse source

commit 5a444bea37 upstream.

Upstream commit aba3a8d01d ("usb: gadget: u_serial: add suspend
resume callbacks") added started_delayed flag, so that new ports
which are opened after USB suspend can start IO while resuming.
But if the port was already opened, and gadget suspend kicks in
afterwards, start_delayed will never be set. This causes resume
to bail out before calling gs_start_io(). Fix this by setting
start_delayed during suspend.
