Forcing the ASYNC_PF_PER_VCPU to be power of two is much easier to be used rather than calling roundup_pow_of_two() from time to time. Do this by adding a BUILD_BUG_ON() inside the hash function. Another point is that generally async pf does not allow concurrency over ASYNC_PF_PER_VCPU after all (see kvm_setup_async_pf()), so it does not make much sense either to have it not a power of two or some of the entries will definitely be wasted.
