[PATCH 1/2] aoe: do not BUG if memory pressure prevented debugfs file creation

[Ed Cashin]

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.
