use clamp_t in UNAME26 fix
commit 31fd84b95eb211d5db460a1dda85e004800a7b52 upstream.
The min/max call needed to have explicit types on some architectures
(e.g. mn10300). Use clamp_t instead to avoid the warning:
kernel/sys.c: In function 'override_release':
kernel/sys.c:1287:10: warning: comparison of distinct pointer types lacks a cast [enabled by default]
