Cliff Wickman c4026cfd8f x86, UV: Initialize BAU hub map
Fix uninitialized uvhub_mask:

- An unitialized bit map variable was causing initialization of
  non-existant hubs (this one causes boot panics).

- And the bit map was too small for large machines.  This patch
  makes it dynamic in size.

- Fix the case where socket 0 has no enabled cpu's. Don't assume
  every hub has a socket 0.

- uv_init_per_cpu() should be __init.
