gpio: mockup: fix a potential crash when creating debugfs entries



If we failed to create the top debugfs directory, we must not try to
create the child nodes. We currently only check if gpio_mockup_dbg_dir
is not NULL, but it can also contain an errno if debugfs is disabled
in build options. Use IS_ERR_OR_NULL() instead.
