  x86, efi: initial the local variable of DataSize to zero (2013-05-14 08:13:05 +0100)

----------------------------------------------------------------
 * Avoid confusing the user by returning -EIO instead of -ENOENT in
   efivarfs if an EFI variable gets deleted from under us and return EOF
   when reading from a zero-length file - Lingzhu Xiang

 * Fix an oops in efivar_update_sysfs_entries() caused by reusing (and
   therefore corrupting) a kzalloc() allocation - Seiji Aguchi

 * Initialise the DataSize argument to GetVariable() otherwise it will
   not be updated with the actual size of the variable on return.
   Discovered on a Acer Aspire V3 BIOS - Lee, Chun-Yi
