Subject: [PATCH] xhci: clear extra bits from slot context when setting max
 exit latency

If we need to change the max exit latency with a Evaluate Context
command, we copy the old output slot context and use it as input
context for the command. This also copies the dev_state bits which
are supposed to be zero in the input slot context.
