math-emu: Fix thinko in _FP_DIV
In commit 48d6c64311ddb6417b901639530ccbc47bdc7635 ("math-emu: Add support for reporting exact invalid exception") code was added to set the new FP_EX_INVALID_{IDI,ZDZ} exception flag bits. However there is a missing break statement for the _FP_CLS_COMBINE(FP_CLS_INF,FP_CLS_INF) switch case, the code just falls into _FP_CLS_COMBINE(FP_CLS_ZERO,FP_CLS_ZERO) which then proceeds to overwrite all of the settings. Fix by adding the missing break. Signed-off-by: David S. Miller <davem@davemloft.net>
