batman-adv: tt: replace open-coded overflow check with helper

Browse source

The commit 6043a632dd06 ("batman-adv: reject oversized global TT response
buffers") introduced an open-coded check to ensure that the allocated
buffer size can be stored in a u16. The check_add_overflow() helper can
perform the addition and overflow check in one step, so use that instead.
