Jason A. Donenfeld be36f9e751 efi: READ_ONCE rng seed size before munmap
This function is consistent with using size instead of seed->size
(except for one place that this patch fixes), but it reads seed->size
without using READ_ONCE, which means the compiler might still do
something unwanted. So, this commit simply adds the READ_ONCE
wrapper.

Fixes: 636259880a ("efi: Add support for seeding the RNG from a UEFI ...")
