[media] m88ds3103: fix undefined division
s32tmp in the below code may be negative, and dev->mclk_khz is an
unsigned type.
s32tmp = 0x10000 * (tuner_frequency - c->frequency);
s32tmp = DIV_ROUND_CLOSEST(s32tmp, dev->mclk_khz);
This is undefined, as DIV_ROUND_CLOSEST is undefined for negative
dividends when the divisor is of unsigned type.
So, change mclk_khz to be signed (s32).
