scsi: qla2xxx: Fix double free of the ha->vp_map pointer

Browse source 
Coverity scan reported potential risk of double free of the pointer
ha->vp_map.  ha->vp_map was freed in qla2x00_mem_alloc(), and again freed
in function qla2x00_mem_free(ha).

Assign NULL to vp_map and kfree take care of NULL.
