MIPS: kvm: Fix ioctl error handling.
Calling return copy_to_user(...) or return copy_from_user in an ioctl
will not do the right thing if there's a pagefault:
copy_to_user/copy_from_user return the number of bytes not copied in
this case.
Fix up kvm on mips to do
return copy_to_user(...)) ? -EFAULT : 0;
and
return copy_from_user(...)) ? -EFAULT : 0;
everywhere.
