KVM: x86: drop unneeded null test

Browse Source 
If the null test is needed, the call to cancel_delayed_work_sync would have
already crashed.  Normally, the destroy function should only be called
if the init function has succeeded, in which case ioapic is not null.

Problem found using Coccinelle.
