commit 78c2106a50e067f7168ee8c0944baaeb0e988272 upstream.
This patch is to fix regression added by commit id 51a07f84649d2be206c4c2ad9a612956db0c2f8c.
When allocating memory for new session original patch does not assign vha to op->vha resulting into NULL pointer access during qlt_create_sess_from_atio().
