powerpc/mm/hash: Remove unnecessary do { } while(0) loop
Avoid coverity false warnings like:
*** CID 187347: Control flow issues (UNREACHABLE)
/arch/powerpc/mm/hash_native_64.c: 819 in native_flush_hash_range()
813 slot += hidx & _PTEIDX_GROUP_IX;
814 hptep = htab_address + slot;
815 want_v = hpte_encode_avpn(vpn, psize, ssize);
816 hpte_v = hpte_get_old_v(hptep);
817
818 if (!HPTE_V_COMPARE(hpte_v, want_v) || !(hpte_v & HPTE_V_VALID))
