Christian Brauner 1783f8c3de keyring-util: pass the buffer size to KEYCTL_DESCRIBE ...

While keyring_describe() allocates a 64 byte buffer it still passes the
value of c as the buffer length. It's -1 on the first iteration. So
keyctl_describe_key() copies the whole description whenever buflen >=
its length. So any key whose description exceeding 64 bytes overflows.
Pass the actual buffer size.
