Revert "USB: core: hub.c: use usb_control_msg_send() in a few places"

Browse source

This reverts commit d6a4992495.
Control messages are needed in contexts when memory allocations
are restricted, such as handling device resets and runtime PM.

For this reason the control message API internally uses GFP_NOIO.
This is a band aid introduced because when we recognized the issue,
the call chains were highly convoluted. Continuing this trend
is not a good idea.

So I am shooting the whole kennel here.
