drm/amdgpu: Replace kzalloc with kcalloc
Replace kzalloc() function with its 2-factor argument form, kcalloc().
This patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a, b, gfp)
Also, improve the coding style and the use of sizeof during
allocation by changing sizeof(struct dc_surface_update) and
sizeof(struct dc_plane_state) to sizeof(*updates) and
sizeof(*surfaces), correspondingly.
This code was detected with the help of Coccinelle.
