bba: Fix config defines

The __is_defined() macro only resolves to 1 if the macro it's used with
is defined to 1; any other value will cause __is_defined() to resolve to
0.

Fix the RX_NOWRAP / TX_SEMA macros that were set, but not properly set
to 1.

    it might be a good idea to protect bba_tx with a semaphore from inside.
