pinctrl: qcom: Handle get_function_mux failure
Presently, get_function_mux returns an unsigned int and cannot
differentiate between failure and correct function value. Change its
return type to int and check for failure in the caller.
Additionally, updated drivers/pinctrl/qcom/pinctrl-*.c to accommodate the
above return type change. Only compile test done.
