v4: add a comment in udp_poll()
v3: drop sk_psock_get_checked()
reuse tcp_bpf_sock_is_readable()
v2: rename and reuse ->stream_memory_read()
fix a compile error in sk_psock_get_checked()

net: rename ->stream_memory_read to ->sock_is_readable
skmsg: extract and reuse sk_msg_is_readable()
net: implement ->sock_is_readable() for UDP and AF_UNIX
