When checking the results of the rte_atomic128_cmp_exchange() function,
current code compares the values of a uint32_t and a uint64_t variable.
If the number of lcores used by the test is large, or the value of the
iteration count N is increased, the variable size mismatch can cause a
false test failure. Modify the comparison to compare uint64_t values.
Fixes: fa3253c534 ("test/atomic: add 128-bit atomic compare exchange test")
