vty: dont put a colon after vty_out in cfg_out macro

The cfg_out macro is used like a function in the code below its
definition. This means a colon will follow after it is used. When
the vty_out call in the macro already has a colon the final result will
be vty_out(...);;. This works fine as long the macro is not used in one
line if/else if/else constructs without curly braces {}. The compiler
will interpret the double colon as two lines of code and run into an
error then. Lets fix this by removing the colon from the vty_cout in the
macro.
