[PATCH 4.9 105/171] module: fix DEBUG_SET_MODULE_RONX typo

[ Upstream commit 4d217a5adccf5e806790c37c61cc374a08bd7381 ]

The newly added 'rodata_enabled' global variable is protected by
the wrong #ifdef, leading to a link error when CONFIG_DEBUG_SET_MODULE_RONX
is turned on:

kernel/module.o: In function `disable_ro_nx':
module.c:(.text.unlikely.disable_ro_nx+0x88): undefined reference to `rodata_enabled'
kernel/module.o: In function `module_disable_ro':
module.c:(.text.module_disable_ro+0x8c): undefined reference to `rodata_enabled'
kernel/module.o: In function `module_enable_ro':
module.c:(.text.module_enable_ro+0xb0): undefined reference to `rodata_enabled'

CONFIG_SET_MODULE_RONX does not exist, so use the correct one instead.

Fixes: 39290b389ea2 ("module: extend 'rodata=off' boot cmdline parameter to module mappings")
