btrfs: fix PAGE_SIZE format specifier in open_ctree()
There is an instance of -Wformat when targeting 32-bit architectures due
to using a 'size_t' specifier (which is 'unsigned int' for 32-bit
platforms) to print PAGE_SIZE:
In file included from fs/btrfs/compression.h:17,
from fs/btrfs/extent_io.h:15,
from fs/btrfs/locking.h:13,
from fs/btrfs/ctree.h:19,
from fs/btrfs/disk-io.c:22:
fs/btrfs/disk-io.c: In function 'open_ctree':
include/linux/kern_levels.h:5:25: error: format '%zu' expects argument of type 'size_t', but argument 4 has type 'long unsigned int' [-Werror=format=]
...
fs/btrfs/disk-io.c:3398:17: note: in expansion of macro 'btrfs_warn'
3398 | btrfs_warn(fs_info,
| ^~~~~~~~~~
PAGE_SIZE is consistently defined as an 'unsigned long' in
include/vsdo/page.h so use '%lu' to clear up the warning.
