[PATCH v2 1/3] usb: renesas_usbhs: Call clk_put()

[Claudiu]

From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>

Clocks acquired with of_clk_get() need to be freed with clk_put(). Call
clk_put() on priv->clks[0] on error path.

Fixes: 3df0e240caba ("usb: renesas_usbhs: Add multiple clocks management")
