xfs: set remote symlink buffer type for recovery
The logging of a remote symlink block does not set the buffer type being logged, and hence on recovery the type of buffer is not recognised and hence CRCs are not calculated after replay. This results in log recoery throwing: XFS (vdc): Unknown buffer type 0 errors, and subsequent reads of the symlink failing CRC verification. Found via fsstress + godown. Reported by: Michael L.
