xhci: remove XHCI_TRUST_TX_LENGTH quirk

xhci: remove XHCI_TRUST_TX_LENGTH quirk

If this quirk was set then driver would treat transfer events with
'Success' completion code as 'Short packet' if there were untransferred
bytes left.

This is so common that turn it into default behavior.

xhci_warn_ratelimited() is no longer used after this, so remove it.

A success event with untransferred bytes left doesn't always mean a
misbehaving controller. If there was an error mid a multi-TRB TD it's
allowed to issue a success event for the last TRB in that TD.

See xhci 1.2 spec 4.9.1 Transfer Descriptors

"Note: If an error is detected while processing a multi-TRB TD, the xHC
 shall generate a Transfer Event for the TRB that the error was detected
 on with the appropriate error Condition Code, then may advance to the
 next TD. If in the process of advancing to the next TD, a Transfer TRB
 is encountered with its IOC flag set, then the Condition Code of the
 Transfer Event generated for that Transfer TRB should be Success,
 because there was no error actually associated with the TRB that
 generated the Event. However, an xHC implementation may redundantly
 assert the original error Condition Code."
