The following warning message "Unrecognised multipath message received" is displayed
in two different situations inside the function multipath_message: when
the number of arguments passed is invalid and when the string passed in argv[0]
is not recognized. With this patch, both warnings are more specific to each case
and is easier to identify where the problem is.
