[PATCH 2/2] LoadPin: Make sysctl table const

Since commit 7abc9b53bd51 ("sysctl: allow registration of const struct
ctl_table"), the sysctl registration API allows for struct ctl_table to be
in read-only memory. Move loadpin_sysctl_table to be declared at build
time, instead of having to be dynamically allocated at boot time.
