xHCI: cancel command after command timeout
commit 6e4468b9a0793dfb53eb80d9fe52c739b13b27fd upstream.
The patch is used to cancel command when the command isn't
acknowledged and a timeout occurs.
This patch should be backported to kernels as old as 3.0, that contain
the commit 7ed603ecf8b68ab81f4c83097d3063d43ec73bb8 "xhci: Add an
assertion to check for virt_dev=0 bug." That commit papers over a NULL
pointer dereference, and this patch fixes the underlying issue that
caused the NULL pointer dereference.
