The validity.verify_base flag should only be set for alias devices. Usually the unit address type is either one of base, PAV alias or HyperPAV alias. But in cases where the unit address type is not set or any other value the validity.verify_base flag might be set as well. This would lead to follow on errors.

The reason is that we assumed we get the perf_top pointer as a signal handler argument which is not the case. Changing the SIGWINCH handler logic to change global resize variable, which is checked in the main thread loop.
