Handle packets with no type byte by returning SSH_MSG_UNIMPLEMENTED.

The previous assertion failure is obviously wrong, but RFC 4253 doesn't
explicitly declare them to be a protocol error.  Currently, the incoming
packet isn't logged, which might cause some confusion for log parsers.

Bug found with the help of afl-fuzz.
