pinctrl: remove superfluous optimization in pinctrl_select_state_locked

As Stephen Warren suggested, checking first if the setting->node entry
is the first in the list or not is superfluous, as it is checked again
in the list_for_each_entry bellow.
So, remove it, the code will be simpler and lighter !
