GFS2: Drop "pull" argument from log_write_header()
The "pull" argument to log_write_header() is only used for debug purposes and it is not really needed any more. There are other tests for this particular problem, so I think we can dispose of it in order to simplify the code. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
