Roman Kagan 4c07f9046e x86/mm, KVM: Fix warning when !CONFIG_PREEMPT_COUNT
A recent commit:

  d6e41f1151 ("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.
