target/hexagon: idef-parser fix leak of init_list

gen_inst_init_args() is called for instructions using a predicate as an
rvalue. Upon first call, the list of arguments which might need
initialization init_list is freed to indicate that they have been
processed. For instructions without an rvalue predicate,
gen_inst_init_args() isn't called and init_list will never be freed.

Free init_list from free_instruction() if it hasn't already been freed.
A comment in free_instruction is also updated.
