x86/mm, KVM: Fix warning when !CONFIG_PREEMPT_COUNT
A recent commit:
d6e41f1151fe ("x86/mm, KVM: Teach KVM's VMX code that CR3 isn't a constant")
introduced a VM_WARN_ON(!in_atomic()) which generates false positives
on every VM entry on !CONFIG_PREEMPT_COUNT kernels.
Replace it with a test for preemptible(), which appears to match the
original intent and works across different CONFIG_PREEMPT* variations.
