target-i386: Check for host features before filter_features_for_kvm() 

commit 5ec01c2e96 broke "-cpu ..,enforce",
as it has moved kvm_check_features_against_host() after the
filter_features_for_kvm() call. filter_features_for_kvm() removes all
features not supported by the host, so this effectively made
kvm_check_features_against_host() impossible to fail.

This patch changes the call so we check for host feature support before
filtering the feature bits.
