[PATCH 3.16 046/245] btrfs: tree-checker: use %zu format string for size_t

From: Arnd Bergmann <arnd@arndb.de>

commit 7cfad65297bfe0aa2996cd72d21c898aa84436d9 upstream.

The return value of sizeof() is of type size_t, so we must print it
using the %z format modifier rather than %l to avoid this warning
on some architectures:

fs/btrfs/tree-checker.c: In function 'check_dir_item':
fs/btrfs/tree-checker.c:273:50: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'u32' {aka 'unsigned int'} [-Werror=format=]

Fixes: 005887f2e3e0 ("btrfs: tree-checker: Add checker for dir item")
