module_enable_rodata_ro() is called twice, once before module init
to set rodata sections readonly and once after module init to set
rodata_after_init section readonly.
The second time, only the rodata_after_init section needs to be
set to read-only, no need to re-apply it to already set rodata.
Split module_enable_rodata_ro() in two.
