usb: core: handle hub C_PORT_OVER_CURRENT condition
Based on USB2.0 Spec Section 11.12.5,
"If a hub has per-port power switching and per-port current limiting,
an over-current on one port may still cause the power on another port
to fall below specific minimums. In this case, the affected port is
placed in the Power-Off state and C_PORT_OVER_CURRENT is set for the
port, but PORT_OVER_CURRENT is not set."
so let's check C_PORT_OVER_CURRENT too for over current condition.
Fixes: 08d1dec6f405 ("usb:hub set hub->change_bits when over-current happens")
