USB: usbip: fix nonconforming hub descriptor
commit ec963b412a54aac8e527708ecad06a6988a86fb4 upstream.
Fix up the root-hub descriptor to accommodate the variable-length
DeviceRemovable and PortPwrCtrlMask fields, while marking all ports as
removable (and leaving the reserved bit zero unset).
Also add a build-time constraint on VHCI_HC_PORTS which must never be
greater than USB_MAXCHILDREN (but this was only enforced through a
KConfig constant).
This specifically fixes the descriptor layout whenever VHCI_HC_PORTS is
greater than seven (default is 8).
Fixes: 04679b3489e0 ("Staging: USB/IP: add client driver")
