[PATCH v8 42/43] KVM: arm64: Expose KVM_ARM_VCPU_REC to user space

Increment KVM_VCPU_MAX_FEATURES to expose the new capability to user
space.

*NOTE*: This also exposes KVM_ARM_VCPU_HAS_EL2/KVM_ARM_VCPU_HAS_EL2_E2H0
(as they are both less than KVM_ARM_VCPU_REC) - so this currently
depends on nested virt being 'finished' before merging.

So this should be merged after: "KVM: arm64: Allow userspace to request
KVM_ARM_VCPU_EL2*":
