netfilter: conntrack: avoid excess memory allocation
This is now a fixed-size extension, so we don't need to pass a variable
alloc size. This (harmless) error results in allocating 32 instead of
the needed 16 bytes for this extension as the size gets passed twice.
Fixes: 23014011ba420 ("netfilter: conntrack: support a fixed size of 128 distinct labels")
