usb: dwc3: Fix lock-up on ID change during system suspend/resume
To reproduce the lock up do the following
- connect otg host adapter and a USB device to the dual-role port
so that it is in host mode.
- suspend to mem.
- disconnect otg adapter.
- resume the system.
If we call dwc3_host_exit() before tasks are thawed
xhci_plat_remove() seems to lock up at the second usb_remove_hcd() call.
To work around this we queue the _dwc3_set_mode() work on
the system_freezable_wq.
Fixes: 41ce1456e1db ("usb: dwc3: core: make dwc3_set_mode() work properly")
