debugfs: Fix filesystem reference counting on debugfs_remove() failure
When __debugfs_remove() fails (because simple_rmdir() fails e.g. when a
directory is not empty), we must not decrement use count of the filesystem
as nothing was in fact deleted.
This fixes use after free caused by debugfs in some cases.
