Currently we call cpu_put_fsr(0) in sparc_cpu_realizefn(), which initializes various fields in the CPU struct: * fsr_cexc_ftt * fcc[] * fsr_qne * fsr It also sets the rounding mode in env->fp_status. This is largely pointless, because when we later reset the CPU this will zero out all the fields up until the "end_reset_fields" label, which includes all of these (but not fp_status!) Move the cpu_put_fsr(env, 0) call to reset, because that expresses the logical requirement: we want to reset FSR to 0 on every reset. This isn't a behaviour change because the fields are all zero anyway.
