xhci: delete endpoints from bandwidth list before freeing whole device

commit 5dc2808c4729bf080487e61b80ee04e0fdb12a37 upstream.

Lists of endpoints are stored for bandwidth calculation for roothub ports.
Make sure we remove all endpoints from the list before the whole device,
containing its endpoints list_head stuctures, is freed.

This used to be done in the wrong order in xhci_mem_cleanup(),
and triggered an oops in resume from S4 (hibernate).
