Yefim Barashkin 1e866f1fe5 drm/amd/pm: Prevent divide by zero
divide error: 0000 [#1] SMP PTI
CPU: 3 PID: 78925 Comm: tee Not tainted 5.15.50-1-lts #1
Hardware name: MSI MS-7A59/Z270 SLI PLUS (MS-7A59), BIOS 1.90 01/30/2018
RIP: 0010:smu_v11_0_set_fan_speed_rpm+0x11/0x110 [amdgpu]

Speed is user-configurable through a file.
I accidentally set it to zero, and the driver crashed.
