efivars: fix size checks in efi_get_variable()

writev() returns the full size, not just the payload size, hence always
add sizeof(attr) where necessary.

Let's also change a couple of "4" into sizeof(attr) all over the place,
to make clear what they are about.

Fixes: #39695
Follow-up for: 9db9d6806e398465a6366dfc5bdde2e24338ac29
