JFS: make sure right-most xtree pages have header.next set to zero

The xtTruncate code was only doing this for leaf pages. When a file is
horribly fragmented, we may truncate a file leaving an internal page with
an invalid head.next field, which may cause a stale page to be referenced.

JFS: make special inodes play nicely with page balancing

This patch fixes up a few problems with jfs's reserved inodes.

1. There is no need for the jfs code setting the I_DIRTY bits in i_state.
I am ashamed that the code ever did this, and surprised it hasn't been
noticed until now.

2. Make sure special inodes are on an inode hash list. If the inodes are
unhashed, __mark_inode_dirty will fail to put the inode on the
superblock's dirty list, and the data will not be flushed under memory
pressure.

3. Force writing journal data to disk when metapage_writepage is unable to
write a metadata page due to pending journal I/O.
