powerpc/64s: Reconnect tlb_flush() to hash__tlb_flush()
Commit baf1ed24b27d ("powerpc/mm: Remove empty hash__ functions")
removed some empty hash MMU flushing routines, but got a bit overeager
and also removed the call to hash__tlb_flush() from tlb_flush().
In regular use this doesn't lead to any noticable breakage, which is a
little concerning. Presumably there are flushes happening via other
paths such as arch_leave_lazy_mmu_mode(), and/or a bit of luck.
Fix it by reinstating the call to hash__tlb_flush().
