usb: xhci-plat: Add XHCI_STATE_REMOVING flag on removal of usb device
Commit 5dcd26f4e903 ("xhci: fix 10 second timeout on removal of PCI
hotpluggable xhci controllers") avoids queueing configure_endpoint
commands for the dropped endpoints.
This change adds XHCI_STATE_REMOVING flag on removal of usb device.
For usb XHCI hotplugged controllers this will prevent 5 second command
timeouts and avoid the races with mutex lock.
