KVM: x86: Track required APICv inhibits with variable, not callback
Track the per-vendor required APICv inhibits with a variable instead of calling into vendor code every time KVM wants to query the set of required inhibits. The required inhibits are a property of the vendor's virtualization architecture, i.e. are 100% static. Using a variable allows the compiler to inline the check, e.g. generate a single-uop TEST+Jcc, and thus eliminates any desire to avoid checking inhibits for performance reasons. No functional change intended.
