sctp: chunk.c: correct format string for size_t in printk

According to Documentation/core-api/printk-formats.rst, size_t should be
printed with %zu, rather than %Zu.

In addition, using %Zu triggers a warning on clang (-Wformat-extra-args):

net/sctp/chunk.c:196:25: warning: data argument not used by format string [-Wformat-extra-args]
                                    __func__, asoc, max_data);
                                    ~~~~~~~~~~~~~~~~^~~~~~~~~
./include/linux/printk.h:440:49: note: expanded from macro 'pr_warn_ratelimited'
        printk_ratelimited(KERN_WARNING pr_fmt(fmt), ##__VA_ARGS__)
        ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
./include/linux/printk.h:424:17: note: expanded from macro 'printk_ratelimited'
                printk(fmt, ##__VA_ARGS__);                             \
                       ~~~    ^
