include/s_user.h: misc cleanup for compiler warning

Browse source 
s_user.c:1428:26: warning: format string is not a string literal
                  [-Wformat-nonliteral]

Adding the printf attribute to the function will make the compiler
assume that the 'format' argument to the function is a string
literal (by warning about the *callers* of the function *not* using
a string literal), thus avoiding the warning in the function.
