Randy Dunlap 786ae133e0 lib: fix test_hmm.c reference after free 
Coccinelle scripts report the following errors:

  lib/test_hmm.c:523:20-26: ERROR: reference preceded by free on line 521
  lib/test_hmm.c:524:21-27: ERROR: reference preceded by free on line 521
  lib/test_hmm.c:523:28-35: ERROR: devmem is NULL but dereferenced.
  lib/test_hmm.c:524:29-36: ERROR: devmem is NULL but dereferenced.

Fix these by using the local variable 'res' instead of devmem.
