batman-adv: make tt_global_add static and return bool

batadv_tt_global_add is not used anymore outside of the TT
code thanks to the TVLV implementation. It can therefore be
declared as static

("batman-adv: tvlv - convert roaming adv packet to use tvlv unicast packets")

Moreover make it return bool since its result can be either 0 or 1.
