Subject: [possible PATCH] crypto: sahara - Use #ifdef DEBUG not
 IS_ENABLED(DEBUG)

Normal use of IS_ENABLED is with a CONFIG_<SYMBOL> and
there is no -DDEBUG in the Makefile here.

Replace the IS_ENABLED(DEBUG) with #ifdef DEBUG/#endif
blocks.

Miscellanea:

o Move the sahara_state array into the function that uses it.
