Harry Wentland f1dfd026cd drm: Don't treat 0 as -1 in drm_fixp2int_ceil 
[ Upstream commit cf8837d7204481026335461629b84ac7f4538fa5 ]

Unit testing this in VKMS shows that passing 0 into
this function returns -1, which is highly counter-
intuitive. Fix it by checking whether the input is
>= 0 instead of > 0.

Fixes: 64566b5e767f ("drm: Add drm_fixp_from_fraction and drm_fixp2int_ceil")
