[PATCH 5.10.y-cip v2 12/27] usb: host: Do not check priv->clks[clk]

From: Claudiu Beznea <[email protected]>

commit a7d5fe02059af66c9759cbf9199e7ed381cc592a upstream.

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.
