memory_libmap: Fix use of uninitialized value for async read ports

Browse source 
The code in memory_libmap expects `clk_en` to be initialized for all
`PortVariant`s but the parsing in memlib.cc didn't initialize it for
variants of kind `PortKind::Ar` (async read ports).

While this fixes the immediate CI failure, it would be best to refactor
the code so it becomes obvious if something isn't initialized.
