mtd: cleanup unused code and variables in fis.c

While compile checking mtd changes in PR#1359 I've noticed following
compiler warnings and cleaned them up:

 fis.c: In function 'fis_remap':
 fis.c:143:25: warning: variable 'redboot' set but not used [-Wunused-but-set-variable]
   struct fis_image_desc *redboot = NULL;
                         ^~~~~~~
 fis.c:142:25: warning: variable 'fisdir' set but not used [-Wunused-but-set-variable]
   struct fis_image_desc *fisdir = NULL;
                         ^~~~~~
