Johannes Berg 8c1bfa7335 cfg80211: fix debugfs rename crash 
commit 0bbab5f0301587cad4e923ccc49bb910db86162c upstream.

Removing the "if (IS_ERR(dir)) dir = NULL;" check only works
if we adjust the remaining code to not rely on it being NULL.
Check IS_ERR_OR_NULL() before attempting to dereference it.

I'm not actually entirely sure this fixes the syzbot crash as
the kernel config indicates that they do have DEBUG_FS in the
kernel, but this is what I found when looking there.

Fixes: d82574a8e5 ("cfg80211: no need to check return value of debugfs_create functions")
