[PATCH -next] ext4: fix the compile error of EXT4_MAX_PAGECACHE_ORDER macro

[Zhang Yi <yi.zhang@huaweicloud.com>]

From: Zhang Yi <yi.zhang@huawei.com>

Since both the input and output parameters of the
EXT4_MAX_PAGECACHE_ORDER should be unsigned int type, switch to using
umin() instead of min(). This will silence the compile error reported by
_compiletime_assert() on powerpc.

Reported-by: Stephen Rothwell <sfr@canb.auug.org.au>
Closes: https://lore.kernel.org/all/20250715082230.7f5bcb1e@canb.auug.org.au/
