xhci: fix sparse warning in xhci-trace.h
This patch fixes the following sparse warnings: drivers/usb/host/./xhci-trace.h:116:1: warning: cast to restricted __le32 drivers/usb/host/./xhci-trace.h:116:1: warning: cast to restricted __le32 drivers/usb/host/./xhci-trace.h:116:1: warning: restricted __le32 degrades to integer drivers/usb/host/./xhci-trace.h:116:1: warning: restricted __le32 degrades to integer by converting the field 'trb' of the trace buffer entry structure from array with elements of type __le32 to an array with elements of type u8. Into the trb array are copied the contents of the TRB that generated the event. The trace-cmd tool with the help of plugin_xhci.py will use this field to parse the TRB contents in a human readable way.
