Zhenzhong Duan f2a02afce6 x86/speculation: Remove redundant arch_smt_update() invocation 
commit 34d66caf251df91ff27b24a3a786810d29989eca upstream.

With commit a74cfffb03b7 ("x86/speculation: Rework SMT state change"),
arch_smt_update() is invoked from each individual CPU hotplug function.

Therefore the extra arch_smt_update() call in the sysfs SMT control is
redundant.

Fixes: a74cfffb03b7 ("x86/speculation: Rework SMT state change")
