GFS2: Don't use a try lock when promoting to a higher mode
Previously we marked all locks being promoted to a higher mode with the try flag to avoid any potential deadlocks issues. The DLM is able to detect these and report them in way that GFS2 can deal with them correctly. So we can just request the required mode and wait for a response without needing to perform this check.
