lib/test_hmm: use kvfree() to free kvcalloc() allocations

Browse Source 
Coccinelle scripts/coccinelle/api/kfree_mismatch.cocci reports
the following warnings:

  lib/test_hmm.c:1256:15-16: WARNING kvmalloc is used to allocate this memory at line 1191
  lib/test_hmm.c:1257:15-16: WARNING kvmalloc is used to allocate this memory at line 1196

Fix this by replacing kfree() with kvfree() to correctly handle the
vmalloc() fallback path of kvcalloc().
