This error is caused by log recovery when mount try to fill super block. As super block is protected by log or Journaling, it shouldn't be corrupted or can't be recovery by journaling.
Anyway, this is reported as XFS INTERNAL ERROR.
XFS internal error XFS_WANT_CORRUPTED_GOTO at line 4147 of file fs/xfs/xfs_bmap.c. Caller 0x871b9c26
