Bartosz Golaszewski bdea98b98f gpio: mockup: fix NULL pointer dereference when removing debugfs ...

commit b7df41a6f79dfb18ba2203f8c5f0e9c0b9b57f68 upstream.

We now remove the device's debugfs entries when unbinding the driver.
This now causes a NULL-pointer dereference on module exit because the
platform devices are unregistered *after* the global debugfs directory
has been recursively removed. Fix it by unregistering the devices first.
