core: always define statements for NL_DBG()
Conditionally defining to nothing, means that the compiler doesn't see
the print statement without NL_DEBUG. In turn, we lack checking of the
statement by the compiler.
Instead, add an "if (NL_DEBUG)" around it. Since NL_DEBUG is a constant, the
compiler will optimize out all the code of the statement, while still
checking it.
