efi/efivars: Set generic ops before loading SSDT
Efivars allows for overriding of SSDT tables, however starting with
commit
bf67fad19e493b ("efi: Use more granular check for availability for variable services")
this use case is broken. When loading SSDT generic ops should be set
first, however mentioned commit reversed order of operations. Fix this
by restoring original order of operations.
