Remove a use of print_expression
The tracepoint code uses print_expression to reconstruct an expression
string. However, the original expression is already available -- it
was just parsed a bit earlier in the same function. This patch
changes this code to simply save the already-parsed expression, rather
than attempt to reconstruct it.
