According to documentation [1], function rte_atomic16_cmpset() return value is non-zero on success; 0 on failure. In existing code this function is called, and the return value is compared to AGE_CANDIDATE, which is defined as 1. Such comparison is incorrect and can lead to unwanted behavior. This patch updates the calls to rte_atomic16_cmpset(), to check that the return value is 0 or non-zero.
