[PATCH][spi-next] spi: stm32: fix range limit checks on div

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

Currently the check for range limits on div is incorrect and will
never return -EINVAL. Fix this by replacing && with ||

Detected by CoverityScan, CID#1446580 ("Structurally dead code")
