ring-buffer-benchmark: Fix the wrong param in module_param 

The {producer|consumer}_{nice|fifo} parameters are integer
type, we should use 'int' as the second param in module_param.

For example(consumer_fifo):
	the default value of consumer_fifo is -1.
   Without this patch:
        # cat /sys/module/ring_buffer_benchmark/parameters/consumer_fifo
        4294967295
   With this patch:
	# cat /sys/module/ring_buffer_benchmark/parameters/consumer_fifo
	-1
