USB: serial: cyberjack: fix write-URB completion race
commit 985616f0457d9f555fff417d0da56174f70cc14f upstream.
The write-URB busy flag was being cleared before the completion handler
was done with the URB, something which could lead to corrupt transfers
due to a racing write request if the URB is resubmitted.
Fixes: 507ca9bc0476 ("[PATCH] USB: add ability for usb-serial drivers to determine if their write urb is currently being used.")
