DES: Silence compiler warnings on Windows
* cipher/des.c (working_memcmp): Make pointer arguments 'const void *'.
--
Following warning seen on Windows target build:
des.c: In function 'is_weak_key':
des.c:1019:40: warning: pointer targets in passing argument 1 of 'working_memcmp' differ in signedness [-Wpointer-sign]
if ( !(cmp_result=working_memcmp(work, weak_keys[middle], 8)) )
^
des.c:149:1: note: expected 'const char *' but argument is of type 'unsigned char *'
working_memcmp( const char *a, const char *b, size_t n )
^
des.c:1019:46: warning: pointer targets in passing argument 2 of 'working_memcmp' differ in signedness [-Wpointer-sign]

^
des.c:149:1: note: expected 'const char *' but argument is of type 'unsigned char *'
