dfilter: fix memory leaks on dfilter compile errors involving a set
If a display filter contains a set for the set membership operator and
an error occurs, then gen_relation_in() (called via dfw_gencode() will
not take ownership of the set and a memory leak occurs.
Fix this by implementing a free callback for STTYPE_SET nodes which
frees unclaimed data. Add tests to verify the effectiveness, ASAN no
longer complains after this fix.
