989d5ec317 xfs: report XFS_IS_CORRUPT errors to the health system
Whenever we encounter XFS_IS_CORRUPT failures, we should report that to
the health monitoring system for later reporting.

I started with this semantic patch and massaged everything until it
built:

@@
expression mp, test;
@@

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

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

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