Subject[PATCH] btrfs: fix size_t format string
Date
The newly added check_block_group_item() function causes a build warning
on 32-bit architectures:

fs/btrfs/tree-checker.c: In function 'check_block_group_item':
fs/btrfs/tree-checker.c:404:41: error: format '%lu' expects argument of type 'long unsigned int', but argument 6 has type 'unsigned int' [-Werror=format=]

The type of a sizeof() expression is size_t, which is correctly printed
using the %zu format string.

Fixes: 9dc16aad5660 ("btrfs: tree-checker: Verify block_group_item")
