Subject: scsi: qla2xxx: Fix double free of the ha->vp_map pointer
From: Saurav Kashyap <skashyap@xxxxxxxxxxx>
commit e288285d47784fdcf7c81be56df7d65c6f10c58b upstream.
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.
