pinctrl: samsung: Fix irq handling if an error occurs in exynos_irq_demux_eint16_31()

Browse Source 
chained_irq_enter(() should be paired with a corresponding
chained_irq_exit().

Here, if clk_enable() fails, a early return occurs and chained_irq_exit()
is not called.

Add a new label and a goto for fix it.
