sysctl: Reduce dput(child) calls in proc_sys_fill_cache() (2024-10-31 11:39:55 +0100)

----------------------------------------------------------------
Summary

* sysctl ctl_table constification

Constifying ctl_table structs prevents the modification of proc_handler
function pointers. All ctl_table struct arguments are const qualified in the
sysctl API in such a way that the ctl_table arrays being defined elsewhere
and passed through sysctl can be constified one-by-one. We kick the
constification off by qualifying user_table in kernel/ucount.c and expect all
the ctl_tables to be constified in the coming releases.

* Misc fixes

Adjust comments in two places to better reflect the code. Remove superfluous
dput calls. Remove Luis from sysctl maintainership. Replace comments about
holding a lock with calls to lockdep_assert_held.

* Testing

All these went through 0-day and they have all been in linux-next for at
least 1 month (since Oct-24). I also rand these through the sysctl selftest
for x86_64.
