of: unittest: Drop if blocks with always false condition
unittest_gpio_remove() is only called after unittest_gpio_probe() completed
successfully. In this case driver data was set to a non-NULL value and so
platform_get_drvdata() never returns NULL.
Also note that the compiler might optimize away this check anyhow as
devptr was already dereferenced for the dev_dbg call above.
Drop this if block.
