bpf, sockmap: fix sock_hash_alloc and reject zero-sized keys
...
Currently, it is possible to create a sock hash map with key size
of 0 and have the kernel return a fd back to user space. This is
invalid for hash maps (and kernel also hasn't been tested for zero
key size support in general at this point). Thus, reject such
configuration.
Fixes: 8111038444 ("bpf: sockmap, add hash map support")
