Remove wtap_block_num_options_of_type().

It's not used; currently, everything that accesses instances of a
multiple-instance-allowed option do so in a loop that iterates over
option instances by fetching values of the Nth option until the attempt
to fetch the option fails, making only one pass over the options.
