usb: core: Strengthen error handling in hub_hub_status()

Browse source

Add additional error handling after the call to get_hub_status() in
hub_hub_status().

get_hub_status() uses usb_control_msg() which does not verify that the
message is the correct length, substituting it for
usb_control_msg_recv() would also solve this issue but increase memory
allocations.

Instead, error handling is copied from the method used in
hub_ext_port_status(), which shares the same flow of logic as
hub_hub_status().
