usb: dwc3: of-simple: fix missing clk_disable_unprepare

Browse source

[ Upstream commit ded600ea9f ]

If of_clk_get() fails, the clean-up of already initialized clocks should be
the same as when clk_prepare_enable() fails. Thus a clk_disable_unprepare()
for each clock should be called before the clk_put().
