dma: debug: no need to check return value of debugfs_create functions
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. Also delete the variables for the file dentries for the debugfs entries as they are never used at all once they are created.
