Yukihiro "Matz" Matsumoto 1c7a0d4e96 vm.c: add type check before calling mrb_hash_size() on keyword dict ...

the keyword argument handling code was checking if kdict is not nil
before calling mrb_hash_size(), but didn't verify it's actually a hash.
malformed bytecode could cause a non-hash value to be stored in the
keyword dictionary register, leading to a NULL pointer dereference in
h_size(). add mrb_hash_p() check to prevent the crash.
