Fix strict-warnings build on FreeBSD
The 'key' member of the (system-defined!) struct session op is of
type c_caddr_t, which can be (signed) char, so inter-casting with the
unsigned char* input to cipher_init() causes -Wpointer-sign errors, and we
can't change the signature of cipher_init() due to the function pointer
type required by EVP_CIPHER_meth_set_init().
As the least-bad option, introduce a void* cast to quell the following
warning:
engines/e_devcrypto.c:356:36: error: passing 'c_caddr_t' (aka 'const char *') to
parameter of type 'const unsigned char *' converts between pointers to integer
types with different sign [-Werror,-Wpointer-sign]
return cipher_init(to_ctx, cipher_ctx->sess.key, EVP_CIPHER_CTX_iv(ctx),
^~~~~~~~~~~~~~~~~~~~
engines/e_devcrypto.c:191:66: note: passing argument to parameter 'key' here
static int cipher_init(EVP_CIPHER_CTX *ctx, const unsigned char *key,
