[patch 7/8 v5] x86, UV: correct failed topology memory leak

[cpw]

Fix a memory leak in init_per_cpu() when the topology check fails.

Signed-off-by: Cliff Wickman <cpw@xxxxxxx>

The leak should never occur after development.  It would only occur in an
unexpected topology that would make the BAU unuseable as a result.
