xfs: report XFS_CORRUPT_ON errors to the health systemcorruption-health-reports_2021-12-15

Whenever we encounter XFS_CORRUPT_ON failures, we should report that to
the health monitoring system for later reporting.

I started with this and massaged everything until it built:

@@
expression mp, test;
@@

- if (XFS_CORRUPT_ON(mp, test)) return -EFSCORRUPTED;
+ if (XFS_CORRUPT_ON(mp, test)) { xfs_btree_mark_sick(cur); return -EFSCORRUPTED; }

@@
expression mp, test;
identifier label, error;
@@

- if (XFS_CORRUPT_ON(mp, test)) { error = -EFSCORRUPTED; goto label; }
+ if (XFS_CORRUPT_ON(mp, test)) { xfs_btree_mark_sick(cur); error = -EFSCORRUPTED; goto label; }
