Brian King bc46257bf4 ixgbevf: Use smp_rmb rather than read_barrier_depends ...

commit ae0c585d93 upstream.

The original issue being fixed in this patch was seen with the ixgbe
driver, but the same issue exists with ixgbevf as well, as the code is
very similar. read_barrier_depends is not sufficient to ensure
loads following it are not speculatively loaded out of order
by the CPU, which can result in stale data being loaded, causing
potential system crashes.
