From: Sung Lee <sung.lee@xxxxxxx>
[WHY]
Previously as MPO + ODM Combine was not supported, finding secondary pipes
for each case was mutually exclusive. Now that both are supported at the same
time, both cases should be taken into account when finding a secondary pipe.
[HOW]
If a secondary pipe cannot be found based on previous bottom pipe,
search for a second pipe using next_odm_pipe instead.
