Distinguish the condition: _DPRINTK_FLAGS_ENABLED from the bit: _DPRINTK_FLAGS_PRINT (and define former as latter), in preparation to add another bit next: _DPRINTK_FLAGS_TRACE And change JUMP_LABEL code block to use the more general _DPRINTK_FLAGS_ENABLED symbol. Also add a 'K' to get new symbol _DPRINTK_FLAGS_PRINTK, in order to break any stale uses.
