[PATCH] drm/nouveau: svm: fix kvcalloc() arguments order

[Dmitry Antipov]

When compiling with gcc version 14.0.0 20231220 (experimental)
and W=1, I've noticed the following warning:

drivers/gpu/drm/nouveau/nouveau_svm.c: In function 'nouveau_svm_fault_buffer_ctor':
drivers/gpu/drm/nouveau/nouveau_svm.c:1014:40: warning: 'kvcalloc' sizes specified with
'sizeof' in the earlier argument and not in the later argument [-Wcalloc-transposed-args]
 1014 |         buffer->fault = kvcalloc(sizeof(*buffer->fault), buffer->entries, GFP_KERNEL);
      |                                        ^

Since 'n' and 'size' arguments of 'kvcalloc()' are multiplied to
calculate the final size, their actual order doesn't affect the
result and so this is not a bug. But it's still worth to fix it.
