glsl2: Early return with visit_continue in loop_analysis::visit(ir_dereference_variable *)

Returning early with visit_continue_with_parent prevented the
then-statements and else-statements of if-statements such as the
following from being processed:

	  if (some_var) { ... } else { ... }

Fixes piglit test case glsl-fs-loop-nested-if and bugzilla #30030.
