USB: usb-skeleton: fix runtime PM after driver unbind
commit 5c290a5e42c3387e82de86965784d30e6c5270fd upstream.
Since commit c2b71462d294 ("USB: core: Fix bug caused by duplicate
interface PM usage counter") USB drivers must always balance their
runtime PM gets and puts, including when the driver has already been
unbound from the interface.
Leaving the interface with a positive PM usage counter would prevent a
later bound driver from suspending the device.
Fixes: c2b71462d294 ("USB: core: Fix bug caused by duplicate interface PM usage counter")
