xhci: Prevent infinite loop in transaction errors recovery for streams

commit a1575120

 upstream.

Make sure to also limit the amount of soft reset retries for transaction
errors on streams in cases where the transaction error event doesn't point
to any specific TRB.

In these cases we don't know the TRB or stream ring, but we do know which
endpoint had the error.

To keep error counting simple and functional, move the current err_count
from ring structure to endpoint structure.
