USB: serial: option: add interface-number sanity check to flag handling
commit a251963f76fa0226d0fdf0c4f989496f18d9ae7f upstream.
Add an interface-number sanity check before testing the device flags to
avoid relying on undefined behaviour when left shifting in case a device
uses an interface number greater than or equal to BITS_PER_LONG (i.e. 64
or 32).
