usb: xhci: utilize 'xhci_free_segments_for_ring()' for freeing segments

Refactor the code to improve readability by using
'xhci_free_segments_for_ring()' function for freeing ring segments.
This replaces the custom while loop previously used within
'xhci_ring_expansion()' and 'xhci_alloc_segments_for_ring()'.

Slightly modify 'xhci_free_segments_for_ring()' to handle lists
which do not loop. This makes it possible to use it in error
paths of 'xhci_alloc_segments_for_ring()'.

This change also prepares for switching the custom xhci linked segment
list into to more standard list.h lists.
