usb: host: Do not check priv->clks[clk]

Browse Source 
There is no need to check the entries in priv->clks[] array before passing
it to clk_disable_unprepare() as the clk_disable_unprepare() already
check if it receives a NULL or error pointer as argument. Remove this
check. This makes the code simpler.
