x86, msr: Have the _safe MSR functions return -EIO, not -EFAULT

Browse source

For some reason, the _safe MSR functions returned -EFAULT, not -EIO.
However, the only user which cares about the return code as anything
other than a boolean is the MSR driver, which wants -EIO.  Change it
to -EIO across the board.
