Subject: [PATCH] cifs: fix debug format string in cifs_debug_data_proc_show

From: Arnd Bergmann <arnd@arndb.de>

Printing a size_t as %lu causes a warning on some architectures:

fs/cifs/cifs_debug.c: In function 'cifs_debug_data_proc_show':
fs/cifs/cifs_debug.c:478:75: error: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'size_t' {aka 'unsigned int'} [-Werror=format=]
  478 |                                 seq_printf(m, "\t\tWeight (cur,total): (%lu,%lu)"

Use the correct %zu format string instead.

Fixes: 962a0fd04791 ("cifs: distribute channels across interfaces based on speed")
