batman-adv: replace non-atomic packet_size_max with (READ|WRITE)_ONCE

The maximum packet size of an meshif is only accessed as plain loads/stores
and does not require full atomic_t semantics. Convert to a native integer
and replace its users with READ_ONCE()/WRITE_ONCE() to avoid load/store
tearing.
