Although CONFIG_VSOCKETS_DIAG depends on CONFIG_VSOCKETS,
vsock_init_tables() is not always called, it is called only
if other modules call its caller. Therefore if we only
enable CONFIG_VSOCKETS_DIAG, it would crash kernel on uninitialized
vsock_bind_table.
This patch fixes it by moving vsock_init_tables() to its own
module_init().
Fixes: 413a4317aca7 ("VSOCK: add sock_diag interface")
