powerpc/64s/hash: Fix stab_rr off by one initialization
[ Upstream commit 09b4438db13fa83b6219aee5993711a2aa2a0c64 ]
This causes SLB alloation to start 1 beyond the start of the SLB.
There is no real problem because after it wraps it stats behaving
properly, it's just surprisig to see when looking at SLB traces.
