pe: Enhance debug report for update_mem_attrs

When memory attributes cannot be updated due to misalignment with 4K or
when the size is 0, the debug printout lacks sufficient clarity to
indicate the issue. To enhance troubleshooting, it is crucial to
generate an error log that explicitly states the failure to execute the
expected action. This error log will be visible even when the debug
level log is not enabled, thereby significantly reducing debugging time.
