x86, hyperv: Move a variable to avoid an unused variable warning

The variable hv_lapic_frequency causes an unused variable warning if
CONFIG_X86_LOCAL_APIC is disabled.  Since the variable is only used
inside a small if statement, move the declaration of that variable
into the if statement itself.
