[SCSI] enclosure: fix oops while iterating enclosure_status array
Based on patch originally by Jeff Mahoney <jeffm@suse.com>
enclosure_status is expected to be a NULL terminated array of strings
but isn't actually NULL terminated. When writing an invalid value to
/sys/class/enclosure/.../.../status, it goes off the end of the array
and Oopses.
Fix by making the assumption true and adding NULL at the end.
