wenyi,xie via groups.io 014b9850f2 MdeModulePkg/FileExplorerLib: Add return value check 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3113
According to FAT specification, the length of file path
should not larger than 260. When the length exceed 260,
function FatLocateOFile will return EFI_INVALID_PARAMETER
and the parameter FileHandle will be NULL. Then on the
top-level function?an exception happens when the NULL
pointer is passed and be used.
So adding return value check after calling
LibGetFileHandleFromMenu, if return value is not success,
stop calling LibFindFiles.
