KVM/x86: Remove superfluous SMP function call
Since the following commit:
1cf4f629d9d2 ("cpu/hotplug: Move online calls to hotplugged cpu")
... the CPU_ONLINE and CPU_DOWN_PREPARE notifiers are always run on the hot
plugged CPU, and as of commit:
3b9d6da67e11 ("cpu/hotplug: Fix rollback during error-out in __cpu_disable()")
the CPU_DOWN_FAILED notifier also runs on the hot plugged CPU. This patch
converts the SMP functional calls into direct calls.
smp_function_call_single() executes the function with interrupts
disabled. This calling convention is not preserved because there
is no reason to do so.
