aoe: do not BUG if memory pressure prevented debugfs file creation
If the system has trouble allocating memory for the creation of the aoe debugfs directory or of a file inside it, the debugfs member of an aoedev can be NULL. Do not treat a NULL debugfs pointer as a BUG on aoedev shutdown, avoiding the user impact of an unecessary panic.
