ASoC: stm32: sai: fix less than zero comparison on unsigned int
Currently, the comparison of div < 0 is always false because div is
an unsigned int. Fix this by making div an int.
Detected by CoverityScan, CID#1475309 ("Unsigned compared against 0")
Fixes: 8307b2afd386 "(ASoC: stm32: sai: set sai as mclk clock provider")
