Mark Fasheh 1fabe1481f ocfs2: Remove struct ocfs2_journal_handle in favor of handle_t
This is mostly a search and replace as ocfs2_journal_handle is now no more
than a container for a handle_t pointer.

ocfs2_commit_trans() becomes very straight forward, and we remove some out
of date comments / code.
