gfs2: Dirty source inode during rename
Mark the source inode dirty during a rename instead of just updating the
underlying buffer head. Otherwise, fsync may find the inode clean and
will then skip flushing the journal. A subsequent power failure will
cause the rename to be lost. This happens in command sequences like:
xfs_io -f -c 'pwrite 0 4096' -c 'fsync' foo
mv foo bar
xfs_io -c 'fsync' bar
# power failure
Fixes xfstests generic/322, generic/376.
