[PATCH BlueZ 03/13] lib: Reuse identical code in sdp_get_{add,}_access_protos()

[Anderson Lizardo <anderson.lizardo@xxxxxxxxxxxxx>]

From: Anderson Lizardo <anderson.lizardo-430g2QfJUUCGglJvpFV4uA@xxxxxxxxxxxxxxxx>

sdp_get_access_protos() and sdp_get_add_access_protos() do almost
exactly the same thing, except for an additional statement for the
latter.
