[PATCH 06/10] xfs: report symlink block corruption errors to the health system

["Darrick J. Wong" <darrick.wong@oracle.com>]

From: Darrick J. Wong <darrick.wong@oracle.com>

Whenever we encounter corrupt symbolic link blocks, we should report
that to the health monitoring system for later reporting.
