[PATCH 3.8-rc4-nohz3] kvm: Add missing EXPORT_SYMBOL_GPL when CONFIG_KVM=m

[Sedat Dilek]

With CONFIG_KVM=m my build with 3.8-rc4-nohz3 breaks like this:

ERROR: "guest_enter" [arch/x86/kvm/kvm.ko] undefined!
ERROR: "guest_exit" [arch/x86/kvm/kvm.ko] undefined!

Fix this by adding the missing EXPORT_SYMBOL_GPL for guest_enter() and
guest_exit() in kernel/context_tracking.c as suggested by Frederic.

This issue was introduced with commit 8eebafe9be58 ("kvm: Prepare to
add generic guest entry/exit callbacks").

[ v2: Add reference to culprit commit. -dileks ]
[ v3: Forgot my S-o-b. -dileks ]
