[GFS2] lockdump improvements
The patch below consists of the following changes (in code order): 1. I fixed a minor compiler warning regarding the printing of a kernel symbol address. 2. I implemented a suggestion from Dave Teigland that moves the debugfs information for gfs2 into a subdirectory so we can easily expand our use of debugfs in the future. The current code keeps the glock information in: /debug/gfs2/<fs> With the patch, the new code keeps the glock information in: /debug/gfs2/<fs>/glock That will allow us to create more debugfs files in the future. 3. This fixes a bug whereby a failed mount attempt causes the debugfs file to not be deleted. Failed mount attempts should always clean up after themselves, including deleting the debugfs file and/or directory.
