x86/smp: Remove unnecessary assignment to local var freq_scale
Coverity warns of an unused value in arch_scale_freq_tick():
CID 100778 (#1 of 1): Unused value (UNUSED_VALUE)
assigned_value: Assigning value 1024ULL to freq_scale here, but that stored
value is overwritten before it can be used.
It was introduced by commit:
e2b0d619b400a ("x86, sched: check for counters overflow in frequency invariant accounting")
Remove the variable initializer.
