This is because env->fp_status is in the part of the CPU state struct that is zeroed on reset. Move the call to set_float_rounding_mode() into the reset fn. (This had no guest-visible effects because it happens that the float_round_nearest_even enum value is 0, so when the struct was zeroed it didn't corrupt the setting.)
