staging: comedi: ni_mio_common: fix the ni_write[blw]() functions



Memory mapped io (dev->mmio) should not also be writing to the ioport
(dev->iobase) registers. Add the missing 'else' to these functions.

Fixes: 0953ee4a ("staging: comedi: ni_mio_common: checkpatch.pl cleanup (else not useful)")
