Since commit 7abc9b53bd51 ("sysctl: allow registration of const struct
ctl_table"), the sysctl registration API allows struct ctl_table variables
to be placed into read-only memory.
mac_hid_files is registered as a sysctl table and should be treated as
read-only. By declaring the mac_hid_files structure as const, we ensure
that it cannot be accidentally modified at runtime. This change improves
safety and aligns with the recommendation from commit 7abc9b53bd51
("sysctl: allow registration of const struct ctl_table").
