usb_hub: fix power cycling logic
When power cycling the hub ports, a misbehaving port will prevent all ports from being powered on because we quit at the first sign of trouble. Skip problematic ports instead of failing the entire power on. Cc: Marek Vasut <marex@denx.de> Cc: Igor Grinberg <grinberg@compulab.co.il> Signed-off-by: Nikita Kiryanov <nikita@compulab.co.il>
