panic: use error_report_end tracepoint on warnings
Introduce the error detector "warning" to the error_report event and use
the error_report_end tracepoint at the end of a warning report.
This allows in-kernel tests but also userspace to more easily determine
if a warning occurred without polling kernel logs.
[akpm@linux-foundation.org: add comma to enum list, per Andy]
