GFS2: Improve tracing support (adds two flags)
This adds support for two new flags. One keeps track of whether
the glock is on the LRU list or not. The other isn't really a
flag as such, but an indication of whether the glock has an
attached object or not. This indication is reported without
any locking, which is ok since we do not dereference the object
pointer but merely report whether it is NULL or not.
Also, this fixes one place where a tracepoint was missing, which
was at the point we remove deallocated blocks from the journal.
