3a7a5e7289 scst_vdisk: Fix handling of vdisk_cmd_params::iv 
Avoid that the iv pointer can become a dangling pointer for
vdisk_fileio devices. Freeing iv without resetting iv_count
makes it namely possible that iv will be used after the memory
that pointer points at has been freed.
    
For vdisk_blockio devices, call vdisk_on_free_cmd_params() to
free the iv pointer.

any functionality.
