Subject: [PATCH v3 1/1] Bluetooth: hci_qca: Cleanup on all setup failures

The setup process previously combined error handling and retry gating
under one condition. As a result, the final failed attempt exited
without performing cleanup.

Update the failure path to always perform power and port cleanup on
setup failure, and reopen the port only when retrying.
