set_reg() is used to write the following MSRs on Xen:

     MSR_FS_BASE
     MSR_KERNEL_GS_BASE
     MSR_GS_BASE

But none of these MSRs are written using any MSR write safe API.
Therefore there is no need to pass an error pointer argument to
set_reg() for returning an error code to be used in MSR safe APIs.

set_seg(), please (further up, too).

Remove the error pointer argument.
