comedi: remove redundant assignment to variable range 

The variable range is being initialized with a value that is never
read, it is being re-assigned later on. The initialization is
redundant and can be removed.

Cleans up clang scan build warning:
drivers/comedi/drivers/das08.c:180:2: warning: Value stored
to 'range' is never read [deadcode.DeadStores]
