PATCH 1/1 GFS2: don't reference inode's glock during block allocation trace

Hi,

This patch changes the block allocation trace so that it references the rgd's glock rather than the inode's glock. Now that the order of inode creation is switched, this prevents a reference to the glock which may not be set yet.

Regards,
