usb: xhci: introduce macro for ring segment list iteration

[ Upstream commit 3f970bd06c5295e742ef4f9cf7808a3cb74a6816 ]

Add macro to streamline and standardize the iteration over ring
segment list.

xhci_for_each_ring_seg(): Iterates over the entire ring segment list.

The xhci_free_segments_for_ring() function's while loop has not been
updated to use the new macro. This function has some underlying issues,
and as a result, it will be handled separately in a future patch.
