ArmPkg/BdsLib: Prevent a hang in BdsConnectDevicePath() when a sub-device path is not found
Some device paths were making BdsConnectDevicePath() hang.
To prevent these hangs we check if the handle returned by
gBS->LocateDevicePath() is the same after each iteration.
An example of a device path that hangs:
PciRoot(0x0)/Pci(0x1,0x0)/USB(0x0,0x0)/USB(0x3,0x0)/HD(...)
The connect controller function manages to find PciRoot()/Pci(0x1,0x0)
but the USB driver does not produce USB(0x0,0x0)/USB(0x3,0x0) and
returns EFI_SUCCESS on its initialization.
