MIPS: Fix enabling of DEBUG_STACKOVERFLOW

Browse source 
commit 5f35b9cd553fd64415b563497d05a563c988dbd6 upstream.

Commit 334c86c494 ("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.
