--------------------------------

[ Upstream commit 1ce69c35 ]

Commit cbf286e8 ("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.
