[GFS2] Fix race in logging code
The log lock is dropped prior to io submittion, but this exposes a hole in which the log data structures may be going away due to a truncate. Store the buffer head in a local pointer prior to dropping the lock and relay on the buffer_head lock for consitency on the buffer head.
