staging: comedi: ni_mio_common: make internal functions static

Browse Source 
The functions ni_release_gpct_mite_channel() and ni_prime_channelgain_list()
are only referenced in this file. Make it static.

The function ni_release_gpct_mite_channel() is also only called
when PCIDMA is enabled. Move the #ifdef to quite a sparse warning
about the function not being used.
