Hao Wu 8c3e4688e0 ShellPkg/Shell: Avoid reading content beyond string boundary 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=690

Within function EfiShellGetDevicePathFromFilePath(), when the input
parameter 'Path' string is like:
"FS0:"

It is possible for the below statement:
"if (*(Path+StrLen(MapName)+1) == CHAR_NULL) {"

to read the content 1 byte beyond the string boundary (both 'Path' and
'MapName' will be FS0: in this case).

This commit adds additional checks to avoid this.
