gpiolib: Fix scope-based gpio_device refcounting

Browse source

[ Upstream commit 832b371097 ]

Commit 9e4555d1e5 ("gpiolib: add support for scope-based management to
gpio_device") sought to add scope-based gpio_device refcounting, but
erroneously forgot a negation of IS_ERR_OR_NULL().

As a result, gpio_device_put() is not called if the gpio_device pointer
is valid (meaning the ref is leaked), but only called if the pointer is
NULL or an ERR_PTR().

While at it drop a superfluous trailing semicolon.
