staging: comedi: ni_labpc: fix legacy driver build
CONFIG_COMEDI_NI_LABPC_ISA is a tristate option. #if IS_ENABLED() needs to be used instead of #ifdef in order to build the legacy specific code in this driver. The local variable 'board' is not used in labpc_attach(). Remove it. The labpc_detach() function is only referenced in this file. Make it static.
