Subject: [PATCH] KVM: x86: fix use of uninitialized memory as segment
 descriptor in emulator.

commit 378a8b099fc207ddcb91b19a8c1457667e0af398 upstream.

If VMX reports segment as unusable, zero descriptor passed by the emulator
before returning. Such descriptor will be considered not present by the
emulator.
