KVM: x86: Force KVM_WERROR if the global WERROR is enabled 



Force KVM_WERROR if the global WERROR is enabled to avoid pestering the
user about a Kconfig that will ultimately be ignored.  Force KVM_WERROR
instead of making it mutually exclusive with WERROR to avoid generating a
.config builds KVM with -Werror, but has KVM_WERROR=n.
