[B.A.T.M.A.N.] [PATCH 02/16] batman-adv: make tt_global_add static and return bool

[Antonio Quartulli <antonio@meshcoding.com>]

From: Antonio Quartulli <ordex@autistici.org>

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

Last user has been removed by 3de4e64df0f1326db7cc0ef25f5af8522850252d
("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.
