x86: SGI UV: Fix BAU initialization

commit e38e2af1c57c3eb5211331a5b4fcaae0c4a2a918 upstream.

A memory mapped register that affects the SGI UV Broadcast
Assist Unit's interrupt handling may sometimes be unintialized.

Remove the condition on its initialization, as that condition
can be randomly satisfied by a hardware reset.
