analyzer: remove unused variables

Fixes:

gcc/analyzer/call-summary.h:103:13: warning: private field 'm_called_fn' is not used [-Wunused-private-field]
gcc/analyzer/engine.cc:1631:24: warning: unused parameter 'uncertainty' [-Wunused-parameter]

gcc/analyzer/ChangeLog:

	* call-summary.cc (call_summary_replay::call_summary_replay):
	  Remove unused variable and arguments.
	* call-summary.h: Likewise.
	* engine.cc (exploded_node::on_stmt): Likewise.
	(exploded_node::replay_call_summaries): Likewise.
	(exploded_node::replay_call_summary): Likewise.
	* exploded-graph.h (class exploded_node): Likewise.
