wireguard: timers: cast enum limits members to int in prints

Since gcc13, each member of an enum has the same type as the enum. And
that is inherited from its members. Provided "REKEY_AFTER_MESSAGES =
1ULL << 60", the named type is unsigned long.

This generates warnings with gcc-13:
  error: format '%d' expects argument of type 'int', but argument 6 has type 'long unsigned int'

Cast those particular enum members to int when printing them.
