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.
