V4L/DVB: smsir: make local variables static

Make the file local parameters static.

This will remove the following sparse warnings (see "make C=1"):
 * warning: symbol 'ir_pos' was not declared. Should it be static?
 * warning: symbol 'ir_word' was not declared. Should it be static?
 * warning: symbol 'ir_toggle' was not declared. Should it be static?
