Antti Palosaari 5b1a2427d4 media: m88ts2022: fix 32bit overflow on filter calc 
commit f538e08513 upstream.

Maximum satellite symbol rate used is 45000000Sps which overflows
when multiplied by 135. As final calculation result is fraction,
we could use mult_frac macro in order to keep calculation inside
32 bit number limits and prevent overflow.

Original bug and fix was provided by Nibble Max. I decided to
implement it differently as it is now.
