Hao Wu 996bd353d2 ShellPkg/Shell: Check the OpenVolume result in OpenRootByHandle()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=779

For the API EfiShellOpenRootByHandle():

The return status of the call to SimpleFileSystem->OpenVolume should be
checked.

It is possible that there is a media change in the device (like CD/DVD
ROM). In such case, the volume root opened and/or the device path opened
previously (also within EfiShellOpenRootByHandle) may be invalid.

This commit adds a check for the result of OpenVolume before subsequently
calling functions like EfiShellGetMapFromDevicePath() &
ConvertEfiFileProtocolToShellHandle().
