analyzer: remove unused field

I added this field (and the struct itself) in the rewrite of region and
value-handling (808f4dfeb3a95f50f15e71148e5c1067f90a126d), but the field
was never used.

Found by cppcheck.

gcc/analyzer/ChangeLog:
	* diagnostic-manager.cc (null_assignment_sm_context::m_visitor):
	Remove unused field.
