x86/tlb: Move __flush_tlb() out of line
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 first step, move __flush_tlb() out of line and hide the native
function. The latter can be static when CONFIG_PARAVIRT is disabled.
Consolidate the namespace while at it and remove the pointless extra
wrapper in the paravirt code.
No functional change.
