powerpc/mm/radix: Properly clear process table entry

Browse source

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.

Fixes: 7e381c0ff6 ("powerpc/mm/radix: Add mmu context handling callback for radix")
