x86/xen: Fix sparse warning in enlighten_pv.c

Browse Source 
[ Upstream commit e5aff444e3a7bdeef5ea796a2099fc3c60a070fa ]

The sparse tool issues a warning for arch/x76/xen/enlighten_pv.c:

   arch/x86/xen/enlighten_pv.c:120:9: sparse: sparse: incorrect type
     in initializer (different address spaces)
     expected void const [noderef] __percpu *__vpp_verify
     got bool *

This is due to the percpu variable xen_in_preemptible_hcall being
exported via EXPORT_SYMBOL_GPL() instead of EXPORT_PER_CPU_SYMBOL_GPL().
