[PULL 2/4] target/i386: Check kvm_hyperv_expand_features() return value

[Paolo Bonzini]

From: Philippe Mathieu-Daudé <phi...@linaro.org>

In case more code is added after the kvm_hyperv_expand_features()
call, check its return value (since it can fail).

Fixes: 071ce4b03b ("i386: expand Hyper-V features during CPU feature expansion 
time")
