To be on the safe side, try to set ro_after_init data section readonly
at the same time as rodata. If it fails it will likely fail again
later so let's cancel module loading while we still can do it.
If it doesn't fail, put it back to read-only, continue module loading
and cross fingers so that it
Once module init has succeded it is too late to cancel loading.
If setting ro_after_init data section to read-only fails, all we
can do is to inform the user through a warning.

Fixes:
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.
