Change magic port number for generic knownhost check.

Browse Source 
libssh2_knownhost_checkp took 0 as a magic port number that indicated
a 'generic' check should be performed.  However, 0 is a valid port
number in its own right so this commit changes the magic value to any
negative int.

\fIport\fP is the port number used by the host (or 0 to check the generic
