Gleb Natapov 64a7ec0668 KVM: Fix unneeded instruction skipping during task switching. 
There is no need to skip instruction if the reason for a task switch
is a task gate in IDT and access to it is caused by an external even.
The problem  is currently solved only for VMX since there is no reliable
way to skip an instruction in SVM. We should emulate it instead.
