thunderbolt: Fix off by one in tb_port_find_retimer()
commit 08fe7ae1857080f5075df5ac7fef2ecd4e289117 upstream.
This array uses 1-based indexing so it corrupts memory one element
beyond of the array. Fix it by making the array one element larger.
Fixes: dacb12877d92 ("thunderbolt: Add support for on-board retimers")
