xfs: report fs corruption errors to the health tracking system

Whenever we encounter corrupt fs metadata, we should report that to the
health monitoring system for later reporting.  A convenient program for
identifying places to insert xfs_*_mark_sick calls is as follows:

#!/bin/bash

# Detect missing calls to xfs_*_mark_sick

filter=cat
tty -s && filter=less

git grep -B3 EFSCORRUPTED fs/xfs/*.[ch] fs/xfs/libxfs/*.[ch] fs/xfs/scrub/*.[ch] | awk '
BEGIN {
	ignore = 0;
	lineno = 0;
	delete lines;
}
{
	if ($0 == "--") {
		if (!ignore) {
			for (i = 0; i < lineno; i++) {
				print(lines[i]);
			}
			printf("--\n");
		}
		delete lines;
		lineno = 0;
		ignore = 0;
	} else if ($0 ~ /mark_sick/) {
		ignore = 1;
	} else if ($0 ~ /if .fa/) {
		ignore = 1;
	} else if ($0 ~ /failaddr/) {
		ignore = 1;
	} else if ($0 ~ /_verifier_error/) {
		ignore = 1;
	} else if ($0 ~ /^ \* .*EFSCORRUPTED/) {
		ignore = 1;
	} else if ($0 ~ /== -EFSCORRUPTED/) {
		ignore = 1;
	} else if ($0 ~ /!= -EFSCORRUPTED/) {
		ignore = 1;
	} else {
		lines[lineno++] = $0;
	}
}
