Subject: [PATCH] qla2xxx: fix kernel NULL pointer access

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().
