[PATCH] staging: comedi: ni_mio_common.c: local functions should be static

[H Hartley Sweeten <hartleys@visionengravers.com>]

Local functions should be marked static to prevent them from
being exposed globally.

This quiets the following sparse warnings:

warning: symbol 'ni_release_gpct_mite_channel' was not declared. Should it be static?
warning: symbol 'ni_prime_channelgain_list' was not declared. Should it be static?
