talk(1) displays incorrect error messages

[Jeff Forys]

Index:	/usr/src/ucb/talk/invite.c 4.3BSD FIX

Description:

	talk(1) returns wrong error message under various circumstances.

Repeat by:

	% talk foo		# where `foo' is someone not logged in
	  [No connection yet]
     >>>  [Target machine does not recognize us]  <<<
	% 

Fix:
	The error messages do not jibe with their respective #define's
	in "/usr/include/protocols/talkd.h".  The solution is to reorder
	the error messages properly as the following diff illustrates...
