netfilter: remove NF_NAT_RANGE_PROTO_RANDOM support
Historically this was net_random() based, and was then converted to
a hash based algorithm (private boot seed + hash of endpoint addresses)
due to concerns of leaking net_random() bits.
RANDOM_FULLY mode was added later to avoid problems with hash
based mode (see commit 34ce324019e76,
"netfilter: nf_nat: add full port randomization support" for details).
Just make prandom_u32() the default search starting point and get rid of
->secure_port() altogether.
