netfilter: nft_set_pipapo: fix null deref for empty set
commit 30c1d25b9870d551be42535067d5481668b5e6f3 upstream.
Blamed commit broke the check for a null scratch map:
- if (unlikely(!m || !*raw_cpu_ptr(m->scratch)))
+ if (unlikely(!raw_cpu_ptr(m->scratch)))
This should have been "if (!*raw_ ...)".
Use the pattern of the avx2 version which is more readable.
This can only be reproduced if avx2 support isn't available.
