Subject: [PATCH] staging: comedi: ni_stc.h: cleanup
 ni_e_series_enable_second_irq()

This function is used to enable/disable the second irq on NI e-series
boards. This irq used used to generate dma requests for the counters.

There are only 2 counters (NUM_GPCT) so the default case of the switch
can never occur.

Tidy up this function and remove the unreachable BUG().
