pinctrl: single: Drop if block with always false condition

pcs_remove() is only called after pcs_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.
