gfs2: Fix xattr fsync
Make sure that changing xattrs marks the corresponding inode dirty so
that a subsequent fsync will sync those changes to disk. We set
I_DIRTY_SYNC as well as I_DIRTY_DATASYNC so that both fsync and
fdatasync will sync xattr changes: xattrs can contain information
critical to how the data can be accessed, so we don't want fdatasync
to skip them.
Fixes xfstest generic/066.
