KVM: Drop stale kvm_is_transparent_hugepage() declaration

kvm_is_transparent_hugepage() was removed in commit 205d76f ("KVM:
Remove kvm_is_transparent_hugepage() and PageTransCompoundMap()") but its
declaration in include/linux/kvm_host.h persisted. Drop it.

Fixes: 205d76f (""KVM: Remove kvm_is_transparent_hugepage() and PageTransCompoundMap()")
