Petr Pavlu 60b57b9cb0 module: Make .static_call_sites read-only after init
Section .static_call_sites holds data structures that need to be sorted and
processed only at module load time. This initial processing happens in
static_call_add_module(), which is invoked as a callback to the
MODULE_STATE_COMING notification from prepare_coming_module().

The section is never modified afterwards. Make it therefore read-only after
module initialization to avoid any (non-)accidental modifications.
