xen/efi: Set nonblocking callbacks 



Other parts of the kernel expect these nonblocking EFI callbacks to
exist and crash when running under Xen. Since the implementations of
xen_efi_set_variable() and xen_efi_query_variable_info() do not take any
locks, use them for the nonblocking callbacks too.
