[PATCH v5 1/6] target/i386: Check kvm_hyperv_expand_features() return value

[Philippe Mathieu-Daudé]

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")
