Use this_cpu_has() instead of boot_cpu_has() to perform the effective
"disabled by BIOS?" checks for VMX. This will allow consolidating code
between vmx_disabled_by_bios() and vmx_check_processor_compat().
Checking the boot CPU isn't a strict requirement as any divergence in VMX
enabling between the boot CPU and other CPUs will result in KVM refusing
to load thanks to the aforementioned vmx_check_processor_compat().
Furthermore, using the boot CPU was an unintentional change introduced by
commit a4d0b2fdbcf7 ("KVM: VMX: Use VMX feature flag to query BIOS
enabling"). Prior to using the feature flags, KVM checked the raw MSR
value from the current CPU.
