MdeModulePkg/Xhci: Add 10ms delay before sending SendAddr cmd to dev

We send ADDRESS DEVICE CMD in XhcInitializeDeviceSlot(), which will
cause XHC issue a USB SET_ADDRESS request to the USB Device.

According to USB spec, there should have a 10ms delay before this
operation after resetting a given port.

But in original code, there is a possible path which may have no such
10ms delay:
UsbHubResetPort()->UsbHubSetPortFeature()->Stall(20)->UsbHubGetPortSt
atus()->XhcPollPortStatusChange()->(if RESET_C bit is set)->
XhcInitializeDeviceSlot()->(if RESET_C bit is set)->Stall(10)

So this patch is used to fix above issue.
