USB: serial: mos7720: fix use-after-free on probe errors
commit 91a1ff4d53c5184d383d0baeeaeab6f9736f2ff3 upstream.
The interrupt URB was submitted on probe but never stopped on probe
errors. This can lead to use-after-free issues in the completion
handler when accessing the freed usb-serial struct:
Unable to handle kernel paging request at virtual address 6b6b6be7
