batman-adv: Remove atomic usage for tt.local_changes

The tt.local_changes atomic is either written with tt.changes_list_lock
or close to it (see batadv_tt_local_event()). Thus the performance gain
using an atomic was limited (or because of atomic_read() impact even
negative). Using atomic also comes with the need to be wary of potential
negative tt.local_changes value.

Simplify the tt.local_changes usage by removing the atomic property and
modifying it only with tt.changes_list_lock held.
