MdeModulePkg: Fix PciBus hang issue
LocatePciExpressCapabilityRegBlock () doesn't check the return status of Pci.Read().
Certain platform's PciRootBridge.Pci.Read() doesn't support PCIE access causing the CapabilityEntry not updated.
If the uninitialized CapabilityEntry equals to a big enough initial value, the while-loop will never end.
