btrfs: tree-checker: use %zu format string for size_t

We now get a harmless compile-time on 32-bit architectures:

fs/btrfs/tree-checker.c: In function 'check_extent_data_item':
fs/btrfs/tree-checker.c:189:70: error: format '%lu' expects argument of type 'long unsigned int', but argument 6 has type 'unsigned int' [-Werror=format=]

This changes the format string to use %zu instead of %lu for size_t.
