pinctrl: ti: ti-iodelay: Drop if block with always false condition

ti_iodelay_remove() is only called after ti_iodelay_probe() completed
successfully. In this case platform_set_drvdata() was called with a
non-NULL argument and so platform_get_drvdata() won't return NULL.

Simplify by removing the if block with the always false condition.
