MdeModulePkg XhciDxe: Set HSEE Bit if SERR# Enable Bit is set

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1167

When the HSEE in the USBCMD bit is a ‘1’ and the HSE bit in the
USBSTS register is a ‘1’, the xHC shall assert out-of-band error
signaling to the host and assert the SERR# pin.
To prevent masking any potential issues with SERR, this patch is
to set USBCMD Host System Error Enable(HSEE) Bit if PCICMD SERR#
Enable Bit is set.
