Subject: [PATCH] Fix segfault when starting a domain with no cpu definition

https://bugzilla.redhat.com/show_bug.cgi?id=996772

My commit fba6bc4 iterated over the features in cpu definition
without checking if there is one.

(cherry picked from commit 1cd8f500ee133653ecb9d1b7f72b2b2e9870a1c3)

Conflicts:
    src/qemu/qemu_migration.c - NBD support missing downstream
    src/qemu/qemu_process.c - downstream doesn't have
        qemuProcessVerifyGuestCPU
