x86/mm/tlb: Restructure switch_mm_irqs_off()
Move some code that will be needed for the lazy -> !lazy state
transition when a lazy TLB CPU has gotten out of date.
No functional changes, since the if (real_prev == next) branch
always returns.
(cherry picked from commit 61d0beb5796ab11f7f3bf38cb2eccc6579aaa70b)
