block: aoe: no need to check return value of debugfs_create functions

2019-06-04T19:38:23+00:00

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.

block drivers/block: Use octal not symbolic permissions

readable.
