x86, UV: remove erroneous BAU initialization

x86, UV: remove erroneous BAU initialization

commit 46814dded1b972a07b1609d81632eef3009fbb10 upstream.

Impact: fix crash on x86/UV

UV is the SGI "UltraViolet" machine, which is x86_64 based.
BAU is the "Broadcast Assist Unit", used for TLB shootdown in UV.

This patch removes the allocation and initialization of an unused table.

This table is left over from a development test mode.  It is unused in
the present code.

And it was incorrectly initialized: 8 entries allocated but 17 initialized,
causing slab corruption.

This patch should go into 2.6.27 and 2.6.28 as well as the current tree.

Diffed against 2.6.28 (linux-next, 12/30/08)
