Patch 2 of 2
The regression was introduced by commit
6ae5ce8e8d4de666f31286808d2285aa6a50fa40.
This patch fixes a regression where the controller firmware version is not
displayed in procfs. The previous patch would be called anytime something
changed. This will get called only once for each controller.
This one addresses the un-needed initialization and the freeing of inq_buf.
Please consider this for inclusion.
