drm/msm/dpu: tidy up some error checking
The "vsync_hz" variable is unsigned int so it can't be less
than zero. The dpu_kms_get_clk_rate() function used to return a u64
but I previously changed it to return an unsigned long and zero on
error so it matches clk_get_rate().
Change the "vsync_hz" type to unsigned long as well and change the
error checking to check for zero instead of negatives. This change
does not affect runtime at all. It's just a clean up.
