Almost everywhere clu is u32, so use U32_MAX instead of UINT_MAX.
The only exception is struct ploop_cmd::resize.clu
which is "unsigned int".
No logic change, just a cleanup.
Fixes: 3e756367e184 ("dm-ploop: Add ploop target driver")
Found while working on https://virtuozzo.atlassian.net/browse/VSTOR-107975
