[ Upstream commit ed14e5903638f6eb868e3e2b4e610985e6a6c876 ]
When tb_ring_alloc_rx() failed in tbnet_open(), ida that allocated in
tb_xdomain_alloc_out_hopid() is not released. Add
tb_xdomain_release_out_hopid() to the error path to release ida.
Fixes: 180b0689425c ("thunderbolt: Allow multiple DMA tunnels over a single XDomain connection")
