[Qemu-devel] [PULL 07/12] target/i386: fix feature check in hyperv-stub.

From: Alex Bennée <address@hidden>

Commit 2d384d7c8 broken the build when built with:

  configure --without-default-devices --disable-user

The reason was the conversion of cpu->hyperv_synic to
cpu->hyperv_synic_kvm_only although the rest of the patch introduces a
feature checking mechanism. So I've fixed the KVM_EXIT_HYPERV_SYNIC in
hyperv-stub to do the same feature check as in the real hyperv.c
