Description

The HandleProtocol() is deprecated interface and we should use OpenProtocol() instead. Moreover, in some firmware implementation(s), the HandleProtocol() does return device path using static storage, so we can not keep the value returned there. With same firmware, the OpenProtocol() does return data we do not need to clone.

Tested by network and disk/cd boot on vmware fusion and bhyve; graphical and serial console, that should cover all use cases.
