If Nt32 is built using UEFI Shell from the ShellPkg sources,
an ASSERT() is generated when a single '\' character is
entered at the shell prompt.
The WinNtSimpleFileSystemDxe module GetNextFileNameToken()
function breaks a file path up into tokens, but it does not
handle the case where a FileName ends in a '\' character.
It returns an empty string instead of NULL. The fix is
to set *FileName to NULL if the remaining file path is an
empty string.
