ocfs2: fix handle refcount leak in two exception handling paths

The reference counting issue happens in two exception handling paths of
ocfs2_replay_truncate_records().  When executing these two exception
handling paths, the function forgets to decrease the refcount of handle
increased by ocfs2_start_trans(), causing a refcount leak.

Fix this issue by using ocfs2_commit_trans() to decrease the refcount of
handle in two handling paths.
