xhci: fix wrong endpoint ESIT value shown in tracing
Read the endpiont ESIT from endpiont context using correct macro. Add a macro for reading the high bits of ESIT for Large ESIT Payload Capable hosts (LEC=1) Cc: <stable@vger.kernel.org> # 4.12 Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
