[v6,40/48] target/ppc/mmu_common.c: Remove yet another single use local

Commit Message

In ppc6xx_tlb_pte_check() the pp variable is used only once to pass it
to a function parameter with the same name. Remove the local and
inline the value. Also use named constant for the hex value to make it
clearer.
