Gary Lin aed5ee6bef efi/x86: Fix the deletion of variables in mixed mode 
[ Upstream commit a4b81ccfd4caba017d2b84720b6de4edd16911a0 ]

efi_thunk_set_variable() treated the NULL "data" pointer as an invalid
parameter, and this broke the deletion of variables in mixed mode.
This commit fixes the check of data so that the userspace program can
delete a variable in mixed mode.

Fixes: 8319e9d5ad98ffcc ("efi/x86: Handle by-ref arguments covering multiple pages in mixed mode")
