When using memcmp function to check data, the third param should be the
size of all elements, rather than the number of the elements.
Furthermore, do code clean up by moving repeated code inside
'test_ring_mem_cmp' function to validate data and print information of
enqueue/dequeue elements if validation fails.
Fixes: a9fe152363e2 ("test/ring: add custom element size functional tests")
