usb: host: xhci: use snprintf() in xhci_decode_trb()
Commit cbf286e8ef83 ("xhci: fix unsafe memory usage in xhci tracing")
apparently missed one sprintf() call in xhci_decode_trb() -- replace
it with the snprintf() call as well...
Found by Linux Verification Center (linuxtesting.org) with the SVACE static
analysis tool.
