drivers/comedi: use standard array-copy-function
comedi_fops.c utilizes memdup_user() to copy a userspace array.
The new function memdup_array_user() provides a standardized way to copy
userspace-arrays. It makes it easier to see that an array is being
copied and, additionally, performs a generic overflow-check which might
help make the code more robust in case of changes in the future.
Replace memdup_user() with memdup_array_user().
