usb: xhci: fix Short Packet handling for isochronous
When Short Packet happens on a multiple-TRBs TD, xHCD needs to
calculate the exact amount of transferred data because upper layer
driver wants it. In order to achieve, xHCD has to:
1. set ISP bit for all TRBs belongs to a IN TD, and
2. set IOC bit for the last TRB of the IN TD.
Once HC detects a Short Transfer, HC will send Short Packet event for
the TRB which encountered Short Packet and also send Short Packet event
fot the last TRB which has IOC bit set.
With those two events, xHCD can calculate the exact amount of bytes which
xHC has completed for the TD. (4.10.1.1)

xhci: fix null-pointer dereference when destroying half-built segment rings
xhci_alloc_segments_for_ring() builds a list of xhci_segments and links
the tail to head at the end (forming a ring). When it bails out for OOM
reasons half-way through, it tries to destroy its half-built list with
xhci_free_segments_for_ring(), even though it is not a ring yet. This
causes a null-pointer dereference upon hitting the last element.
Furthermore, one of its callers (xhci_ring_alloc()) mistakenly believes
the output parameters to be valid upon this kind of OOM failure, and
calls xhci_ring_free() on them. Since the (incomplete) list/ring should
already be destroyed in that case, this would lead to a use after free.
This patch fixes those issues by having xhci_alloc_segments_for_ring()
destroy its half-built, non-circular list manually and destroying the
invalid struct xhci_ring in xhci_ring_alloc() with a plain kfree().
This patch should be backported to kernels as old as 2.6.31, that
contains the commit 0ebbab37422315a5d0cb29792271085bafdf38c0 "USB: xhci:

A separate patch will need to be developed for kernels older than 3.4,
since the ring allocation code was refactored in that kernel.

xHCI: handle command after aborting the command ring
