ASoC: stm: stm32_i2s: Fix calc_clk_div() error handling in determine_rate()
calc_clk_div() will only return a non-zero value (-EINVAL)
in case of error. On the other hand, req->rate is an unsigned long.
It seems quite odd that req->rate would be assigned a negative value,
which is clearly not a rate, and success would be returned.
Reinstate previous logic, which would just return error.
