mbedtls: avoid warning with GCC 13+

crypto_mbedtls.c:568:1: error:
conflicting types for ‘cipher_ctx_init’ due to enum/integer mismatch;
have ‘void(mbedtls_cipher_context_t *, const uint8_t *, const char *, const mbedtls_operation_t)’
[...] [-Werror=enum-int-mismatch]
crypto_backend.h:341:6: note:
previous declaration of ‘cipher_ctx_init’ with type
‘void(cipher_ctx_t *, const uint8_t *, const char *, int)’ [...]

Previous compiler versions did not complain.
