usb: xhci-mtk: fix bandwidth release issue
This happens when @udev->reset_resume is set to true, when usb resume,
the flow as below:
- hub_resume
- usb_disable_interface
- usb_disable_endpoint
- usb_hcd_disable_endpoint
- xhci_endpoint_disable // it set @ep->hcpriv to NULL
Then when reset usb device, it will drop allocated endpoints,
the flow as below:
- usb_reset_and_verify_device
- usb_hcd_alloc_bandwidth
- xhci_mtk_drop_ep
but @ep->hcpriv is already set to NULL, the bandwidth will be not
released anymore.
Due to the added endponts are stored in hash table, we can drop the check
of @ep->hcpriv.
