[PATCH 55/57] staging: comedi: drivers: ni_mio_common: Move 'range_ni_E_ao_ext' to where it is used

[Lee Jones]

... and mark it as __maybe_unused since not all users of the
header file reference it.

Fixes the following W=1 kernel build warning(s):

 drivers/staging/comedi/drivers/ni_mio_common.c:163:35: warning: 
‘range_ni_E_ao_ext’ defined but not used [-Wunused-const-variable=]
