 module mappings

Hi Akashi,

your patch "module: extend 'rodata=off' boot cmdline parameter to module
mappings" showed up in linux-next today, and I noticed a small error in it.

The first modified #ifdef is fine, the second one, however, has a spelling
mistake in it: the CONFIG_ variable should be CONFIG_DEBUG_SET_MODULE_RONX
instead of CONFIG_SET_MODULE_RONX (note the missing DEBUG).

I noticed it by running 'scripts/checkkconfigsymbols -f --force -f
next-20161124..next-20161128', which is essentialy diffing the last two
linux-next releases and looks for undefined/unknown Kconfig symbols.
You can also run the script on single commits with -c to test them.

Best regards,

Andreas
