Subject: [PATCH] pinctrl: Delete unnecessary checks before the function call "pinctrl_unregister"

The pinctrl_unregister() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
