Do not write-protect the kernel read-only and __ro_after_init sections
earlier than before mark_rodata_ro() is called. This fixes a boot issue on
parisc which is triggered by commit 91a1d97ef482 ("jump_label,module: Don't
alloc static_key_mod for __ro_after_init keys"). That commit may modify
static key contents in the __ro_after_init section at bootup, so this
section needs to be writable at least until mark_rodata_ro() is called.
