ppc: Fix migration of the XER register 



env->xer only holds the lower bits of the XER register nowadays, the
SO, OV and CA bits are stored in separate variables (see the function
cpu_write_xer() for details). Since the migration code currently only
reads the "xer" variable, the upper bits are lost during migration.
Fix it by using cpu_read_xer() instead.
