xhci: Fix missing break in xhci_evaluate_context_result.
Coverity complains that xhci_evaluate_context_result() is missing a
break statement after the COMP_EBADSLT switch case. It's not a big
deal, since we wanted to return the same error code as the case
statement below it does. The end result would be one that a Slot
Disabled error completion code would also print the warning message
associated with a Context State error code. No other bad behavior would
result.
It's not worth backporting to stable kernels, since it only fixes an
issue with too much debugging.
