heary-cao 9f3d1407dc Fix zfs_allow_log_destroy() NULL dereference 
In zfs_ioc_log_history() function the tsd_set() function is called
with NULL which causes the zfs_allow_log_destroy() to be run.  In
this case the passed value will be NULL.  This is normally entirely
safe because strfree() maps directly to kfree() which may be passed
a NULL.  However, since alternate implementations of strfree() may
not handle this gracefully add a check for NULL.

Observed under an embedded Linux 2.6.32.41 kernel running the
automated testing while running the ZFS Test Suite.
