Subject: [PATCH V4][next] Bluetooth: btintel_pcie: Remove structrually deadcode

The switch case statement has a default branch. Thus, the return
statement at the end of the function can never be reached.
Fix it by removing the return statement at the end of the
function.

This issue was reported by Coverity Scan.

Fixes: 5ea625845b0f ("Bluetooth: btintel_pcie: Add handshake between driver and firmware")
