Subject: [PATCH 1/1] MdeModulePkg/XhciDxe: Reset endpoint while USB Transaction error

https://bugzilla.tianocore.org/show_bug.cgi?id=4556

Based on XHCI spec 4.8.3, software should do the reset endpoint while USB Transaction occur.
Also add the error code for USB Transaction error since UEFI spec don't have the related definition.
