runtime: disable event scanning error reporting on solaris

It seems like we need to pay special attention to capturing error
condition on the event port of SmartOS. The previous attempt CL 167777
works on Oracle Solaris but doesn't work on SmartOS for the uncertain
reason. It's better to disable the reporting for now.

Updates #30624.
Fixes #30840.
