Fix when gatt disconnect too fast, RC pair fail

[Root Cause]
when disconnect too fast and link_state is still DISCONNECTED,
in release_ccb, only lcb released, ACL link will not removed.
When this case happend, disc_comp will have no lcb,
then auto connection will fail cuz last ACL exists.

[Solution]
Set link_state as LST_CONNECTING to avoid this case.
