[POWERPC] Remove barriers from the SLB shadow buffer update

Browse source

After talking to an IBM POWER hypervisor (PHYP) design and development
guy, there seems to be no need for memory barriers when updating the SLB
shadow buffer provided we only update it from the current CPU, which we
do.

Also, these guys see no need in the future for these barriers.
