Marcel (and reviewers),

Now if we are having both error_report_fatal() and
error_report_abort(), we'll write error_report() three times if we all
take them as functions.

How about we still use macro this time but leverage error_setg()
macro as mentioned by Fam, like:

+#define error_report_fatal(...) error_setg(&error_fatal, __VA_ARGS__)
+#define error_report_abort(...) error_setg(&error_abort, __VA_ARGS__)

In this case, we avoided calling exit() directly in the macro, and is
much cleaner than writting error_report() content for three times.
