USB: serial: ch341: handle unbound port at reset_resume
commit 4d5ef53f75c22d28f490bcc5c771fcc610a9afa4 upstream.
Check for NULL port data in reset_resume() to avoid dereferencing a NULL
pointer in case the port device isn't bound to a driver (e.g. after a
failed control request at port probe).
Fixes: 1ded7ea47b88 ("USB: ch341 serial: fix port number changed after resume")
