tools: ynl: check for null ptr on dump free
Static analysis detected code paths where freeing a dump list after early
errors when creating the corresponding dump list like in ynl_exec_dump()
can result in a null pointer dereference since the first node in the
ynl_dump_state would still be zero initialized. To prevent this potential
problem updated the ynl c generation script to check for a NULL pointer
before continuing to free the nodes in a dump list.
