IB/core: Fix static analysis warning in ib_policy_change_task

ib_get_cached_subnet_prefix can technically fail, but the only way it
could is not possible based on the loop conditions. Check the return
value before using the variable sp to resolve a static analysis warning.

-v1:
- Fix check to !ret. Paul Moore
