cpu_tlbstate is exported because various TLB-related functions need access
to it, but cpu_tlbstate is sensitive information which should only be
accessed by well-contained kernel functions and not be directly exposed to
modules.
As a third step, move _flush_tlb_one_user() out of line and hide the
native function. The latter can be static when CONFIG_PARAVIRT is
disabled.
Consolidate the name space while at it and remove the pointless extra
wrapper in the paravirt code.
No functional change.
