Subject: xhci: Don't use a dummy endpoint count in configure command.
X-Git-Tag: rel-1.7.5-rc1~58

xhci: Don't use a dummy endpoint count in configure command.

At least some real-world controllers expect the endpoint count in the
inctx to be accurate, so set it to the pipe currently being activated.
