[PULL 2/6] i386/cpu: Don't add unavailable_features to env->user_features

[Eduardo Habkost <ehabkost@redhat.com>]

From: Xiaoyao Li <xiaoyao.li@intel.com>

Features unavailable due to absent of their dependent features should
not be added to env->user_features. env->user_features only contains the
feature explicity specified with -feature/+feature by user.

Fixes: 99e24dbdaa68 ("target/i386: introduce generic feature dependency mechanism")
