Remove unsued variable.

If we are not transfering any data, use a non S/G ccb type that doesn't
return residual information.  It seems that some firmware revisions dislike
S/G ccbs with 0 length S/G lists.

Correct bt_cmd() so that we always honor command status that was latched
by our interrupt routine while polling for completion..
