[PATCH] libosmo-sccp[master]: get rid of global osmo_ss7_xua_servers variable

[Harald Welte]

Review at  https://gerrit.osmocom.org/2350

get rid of global osmo_ss7_xua_servers variable

By moving this variable into the SS7 instance, we avoid one more global
variable, and we also fix a bug where the xua servers would be saved
multiple times (once per instance).
