USB: xHCI: change xhci_reset_device() to allocate new device

Browse Source 
Rename xhci_reset_device() to xhci_discover_or_reset_device().
If xhci_discover_or_reset_device() is called to reset a device which does
not exist or does not match the udev, it calls xhci_alloc_dev() to
re-allocate the device.

This would prevent the reset device failure, possibly due to the xHC restore
error during S3/S4 resume.
