-hw_random carefully avoids using a stack buffer except in
-add_early_randomness().  This causes a crash in virtio_rng if
-CONFIG_VMAP_STACK=y.

-Reported-by: Matt Mullins <mmullins@mmlx.us>

-Fixes: d3cc7996473a ("hwrng: fetch randomness only after device init")

-This fixes a crash in 4.9-rc1.

-resending because I typoed the git send-email command.  I stealthily added
