[PATCH] drm/amdgpu: Use kmalloc_array() instead of kmalloc()

[Rahul Kumar]

Documentation/process/deprecated.rst recommends against the use of
kmalloc with dynamic size calculations due to the risk of overflow and
smaller allocation being made than the caller was expecting.

Replace kmalloc() with kmalloc_array() in amdgpu_amdkfd_gfx_v10.c
to make the intended allocation size clearer and avoid potential
overflow issues.
