Currently osd caching statistics are not reported or compiled for zfs.

Upon fixing this sanity test_156 should be re-enabled for ZFS (see LU-1956)

The simplest fix seems to be to add a version test to sanity test_156. The problem is the patch for LU-4259 landed right after 2.6.92 so do we check for version 2.6.93? It will be awhile before that tag happens.
