gnss: sirf: fix activation retry handling
Fix activation helper which would return -ETIMEDOUT even if the last
retry attempt was successful.
Also change the semantics of the retries variable so that it actually
holds the number of retries (rather than tries).
Fixes: d2efbbd18b1e ("gnss: add driver for sirfstar-based receivers")
