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.
