* Fix IndexError in free strategy when hosts become unreachable
Fixes an IndexError crash in the free strategy plugin when hosts
become unreachable during playbook execution.
The bug occurred when:
- last_host index persists across outer loop iterations
- hosts_left is regenerated each iteration via get_hosts_left()
- Some hosts become unreachable between iterations
- hosts_left shrinks but last_host retains its previous value
- Accessing hosts_left[last_host] raises IndexError
The fix adds a bounds check after regenerating hosts_left to reset
last_host to 0 if it's out of bounds. This preserves the round-robin
fairness algorithm while preventing the IndexError.
