usb: dwc3: of-simple: fix missing clk_disable_unprepare


[ Upstream commit ded600ea9fb51a495d2fcd21e90351df876488e8 ]

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().

Found by Linux Driver Verification project (linuxtesting.org).
