[PATCH 2/5] GPU-DRM: Replace two kzalloc() calls by kcalloc() in drm_legacy_addbufs_pci()

[SF Markus Elfring]

From: Markus Elfring

The script "checkpatch.pl" can point information out like the following.

WARNING: Prefer kcalloc over kzalloc with multiply

Thus fix the affected source code places.
