analyzer: fix param "analyzer-max-enodes-per-program-point"

This was effectively checking for one beyond the limit, rather than
the limit itself.

Seen when fixing PR analyzer/97514.

gcc/analyzer/ChangeLog:
	* engine.cc (exploded_graph::get_or_create_node): Fix off-by-one
	when imposing param_analyzer_max_enodes_per_program_point limit.
