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.
