x86/cpu: Use EXPORT_PER_CPU_SYMBOL_GPL() for x86_spec_ctrl_current

Browse Source 
Sparse rightfully complains:

  bugs.c:71:9: sparse: warning: incorrect type in initializer (different address spaces)
  bugs.c:71:9: sparse:    expected void const [noderef] __percpu *__vpp_verify
  bugs.c:71:9: sparse:    got unsigned long long *

The reason is that x86_spec_ctrl_current which is a per CPU variable is
exported with EXPORT_SYMBOL_GPL().

Use EXPORT_PER_CPU_SYMBOL_GPL() instead.
