Commit 334c86c494b9 ("MIPS: IRQ: Add stackoverflow detection") added kernel stack overflow detection, however it only enabled it conditional upon the preprocessor definition DEBUG_STACKOVERFLOW, which is never actually defined. The Kconfig option is called DEBUG_STACKOVERFLOW, which manifests to the preprocessor as CONFIG_DEBUG_STACKOVERFLOW, so switch it to using that definition instead.
