Default GFS2: Add more detail to debugfs glock dumps

From: Steven Whitehouse <swhiteho@redhat.com>

Although the glock dumps print quite a lot of information about
the glocks themselves, there are more things which can be
usefully added to the dump realting to the objects themselves.

This patch adds a few more fields to the inode and resource
group lines, which should be useful for debugging.
