The only use of this function in kvm.c is right after using the KVM
ioctl to get the registers themselves, so there is no need to do the
error checks done by ppc_store_sdr1.
The probable reason this was here before is because of the hack where
KVM PR stores the hash table size along with the SDR1 information, but
since ppc_store_sdr1 would also store that information, there should be
no need to do any extra processing here.

This change means we won't have to compile ppc_store_sdr1 when we get
disable-tcg working, but I'm not working on that code motion just yet
since Lucas is dealing with the same file.
I'm sending this as an RFC because I'm pretty sure I'm missing
something, but from what I can see, this is all we'd need
