ASoC: stm: Prevent potential division by zero in stm32_sai_mclk_round_rate()

Browse source

[ Upstream commit 63c1c87993 ]

This patch checks if div is less than or equal to zero (div <= 0). If
div is zero or negative, the function returns -EINVAL, ensuring the
division operation (*prate / div) is safe to perform.
