powerpc/mm/radix: Properly clear process table entry
commit c6bb0b8d426a8cf865ca9c8a532cc3a2927cfceb upstream.
On radix, the process table entry we want to clear when destroying a
context is entry 0, not entry 1. This has no *immediate* consequence
on Power9, but it can cause other bugs to become worse.
