usb: fotg210-udc: fix potential memory leak in fotg210_udc_probe()

In fotg210_udc_probe(), if devm_clk_get() or clk_prepare_enable()
fails, 'fotg210' will not be freed, which will lead to a memory leak.
Fix it by moving kfree() to a proper location.

In addition，we can use "return -ENOMEM" instead of "goto err"
to simplify the code.
