usb: dwc3: of-simple: fix clock resource leak in dwc3_of_simple_probe

Browse source

commit 3b4961313d upstream.

When clk_bulk_prepare_enable() fails, the error path jumps to
err_resetc_assert, skipping clk_bulk_put_all() and leaking the
clock references acquired by clk_bulk_get_all().

Add err_clk_put_all label to properly release clock resources
in all error paths.

Found via static analysis and code review.
