staging: unisys: visornic: no need to check debugfs return values
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Clean up the visornic driver code by not caring about the value of debugfs calls. This ends up removing a number of lines of code that are not needed.
