Fix md_kt_size in mbed TLS when queried for size of "none"
Previously this would error out with a M_FATAL message about cipher
not known. Align the mbed TLS version to OpenSSL version and also remove
unreachable code. This manifested in key_print2() running into this
M_FATAL message when used with an AEAD cipher and verb 7.
