[rsync] memory leak in 2.5.5

[Lars J. Buitinck]

there is a memory leak in set_compression(), token.c:

	dont = strdup(dont);
	fname = strdup(fname);
	if (!dont || !fname) return;

if strdup(fname) fails but strdup(dont) doesn't, the memory pointed to 
by dont is leaked, and vice versa.  this may not be much but I believe 
one of set_compression()'s ancestors is invoked inside a loop when in 
server mode.  correct would be:

	if ((dont = strdup(dont)) == NULL
	 || (fname= strdup(fname))== NULL)
		return;

ps.: I'm not on this list.
