When compiling btrfs-progs on 32bit x86 using GCC 11.1.0, there are
several warnings:
In file included from ./common/utils.h:30,
from check/main.c:36:

There are two types of problems:
- __BTRFS_LEAF_DATA_SIZE()
This macro has no type definition, making it behaves differently on
different arches.
Fix this by following kernel to use inline function to make its return
value fixed to u32.
- size_t related output
For x86_64 %lu is OK but not for x86.
Fix this by using %zu.
